Pre-Lab Questions 1. Hypothesize why a fungus would use spores as a mechanism for reproduction. * Spores are small and light and can help fungus reproduce both sexually and asexually. A fungus would use a spore to reproduce because when they land in the right conditions, they germinate and grow new hyphae.

2. How might the environment affect a fungus reproducing sexually or asexually?

* Because if the environment is not how it needs to be the fungus will be unable to grow

3. What characteristics are more plant-like? Animal-like?

* With animals fungi lack chloroplasts and with plants fungi have a cell wall and vacuoles, the produce sexually and asexually

Post-Lab Questions

1. Include your hypothesis from Step 5 here.

* I believe that the wet piece of bread will experience more growth over time than the dry piece of bread. The bread will act as a sponge, soak up the water, and fungus and bacteria will start to grow over the course of a few days.

2. What structures did you see in the bread mold?

* Different color molding, mostly yellowish white molds, rough surface, large oval or circular structures, some places were very hard and dry as well.

3. Why was it important to moisten the bread before sealing it in the resealable bag?

* I believe it was important because moistening the bread will allow mold to grow quicker when kept in an incubated location

4. What type of control (positive or negative) did the dry bread provide? Explain why.

* Negative results because placing the dry piece of bread would be the same as keeping in the bread bag. There are no host cells in the bag that would create a mold to grow so fast even though bread does mold, but only over a longer period of time.

5. Is the bread mold reproducing sexually or asexually? How…...

Helper Questions About Fungi

...Question about topic: Why does fungus grow in caves more than out in the open sun? Background Information: Fungi enjoy living in damp and dank areas. For example near large water sources, such as, rivers, streams, and springs in the woods. They are unable to be self-sufficient due to being unable to produce their own food independently with photosynthesis. They must absorb nutrients vital to sustain themselves that is most readily found in woods or forests with water sources in or near by them. The fallen leaves and flowing water bring many nutrients to them through the flow of the water as well as the decay of the leaves that contain some of the nutrients of the tree it once was a part of. They are also capable of living inside plants and animals. Also aiding in the decomposition and fertilization, fungi help decompose plant and animal materials (i.e. waste, flesh, etc.). My hypothesis: I hypothesize that fungi grow in dark areas with water sources and other miscellaneous animal traffic due to the independence from the sun and animal traffic leaving waste and other materials as they come and go. Experiment: The experiment is to first purchase fungi and split them into two equal amounts. Once separated take the first half and plant them next to the flowing water source leaving openly exposed to the sun. Next take the left over half of fungi, plant them in a dark closed in area with the flowing water, such as a wood box flipped upside down. Once that is done set...

...protozoa, fungi and Viruses. The modes of action when the pathogens get into the host organism are similar. They first multiply then start destroying different tissues and cells in the host organism. They may release toxins that make the host environment conducive for their survival. The toxins harm the cells of the host organism, thus leading to different illnesses. The illnesses caused are normally very infectious, and they may lead to epidemics. This paper will compare and contrast the pathogens causing whooping cough and zygomycosis. Causal pathogens Whooping cough and Zygomycosis are some of the infectious diseases caused by different pathogens. In whooping cough, the pathogen infects the respiratory system, causing severe coughing in the victims. It is caused by the bacteria Bordetella pertussis. Zygomycosis is a broad range of fungal infectious diseases that affect the face; particularly the nasal cavity, and the eyes as well as the skin. It is caused by fungi in the Mucorales and Entomophthorales (Vazquez Para 1). The pathogens causing whooping cough and Zygomycosis have several similarities and differences. Classification Bordetella Pertussis belongs to the Kingdom Bacteria, and it is in the phylum Proteobacteria. The bacteria are in the class Beta Proteobacteria and order Burkholderiales. It belongs to the Alcaligenaceae family under the genus Bordetella. The bacterium is of the species B. Pertussis (Locht 31). Mucorales belong to the Kingdom Fungi,......

Fungus Among Us

...staphylococci by a mold. He noticed a bacteria-free circle around the mold growth and discontinued his project to focus on his accidental observation. The mold, a member of the fungi kingdom, was isolated and identified as Penicillium Notatum. When the mold was allowed to grow on culture plates and different bacteria were streaked across the plate; Fleming observed that some grew up to the mold while others were inhibited. This observation made Fleming conclude that Penicillium Notatum produced an antibacterial substance that inhibited some bacteria while not inhibiting others. The antibiotic produced from this member of the Fungi Kingdom is what we now know as Penicillin (Wennergren & Lagercrantz, 2006). Mold is just one member of the Fungi Kingdom. Fungi can be found everywhere in the world including the air, water, soil and on plants or animals. The fungi reproduction cycle is truly unique compared to all other eukaryotic organisms. They produce sexually and asexually with some organisms of fungi only reproducing asexually (Liang, 2005). During the life cycle of fungi they produce spores and from these spores haploid hyphae grow, split and branch out. For which this process may give rise to asexual sporangia, which is a special hyphae that produces spores without undergoing meiosis (Berkeley, 2008). In fungi the zygote is the only diploid cell and when two mating types fuse; the two nuclei coexist until the right conditions are present. After fusion is completed,......

Marine Fungi; a Review

...roughly 500 species of obligate marine fungi. Much of said research was conducted from 1980-2000; this 30 year period saw the report of nearly half of the marine fungal species currently known (Jones et al. 2009; Jones, 2011). That being said, marine fungi are vastly understudied and under rated in comparison to marine plants, animals, and other microorganisms; frequently they are omitted or only briefly referenced in marine biodiversity and ecology text books (Jones and Pang, 2012). The cladistics of marine fungi is currently in a state of flux, with new taxa being discovered as molecular techniques such as DNA and RNA analysis via polymerase chain reactions, and gel electrophoresis are implemented (Ald et al 2005). Even though fungus-like organisms such as oomycetes are not fungi, marine mycologists often study them as they perform similar functions, and until recently most had been classified as fungi based on their morphological similarities (Jones, 2011). These fungus-like organisms are eukaryotic, heterotrophic, zoospores, have chitin containing cell walls, and similar life cycles to fungi (Neuhauser et al. 2012). Conventionally terrestrial or freshwater species are also included in the marine fungal group as facultative species; this is due to their active ecological role in the marine, and estuarine environment. Here is broad, but accepted definition for obligate, and facultative marine fungi from Kohlmeyer, 1979 "obligate marine fungi are those that grow and......

...absorb their nutrients from the decaying bodies of plants and animals. This is the fungus known to mold bread, specifically called Rhizopus stonlonifer, but on the beneficial side certain species of this fungi is used to ferment some Asian foods and kill insects. This fungus is the cause of infections, particularly zygomycetes, in humans affecting diabetics and immunocomprimised patients called zygomycosis. Ascomycota, this fungus includes molds and yeasts. It is also know as sac fungi, because of the ascus, and reproduces asexually with spores called conidia because they float in the air like dust. They form their ascospores by fusing nuclei of two cells, which are morphologically alike nor not. Ascomycota are heterotrophs and get their nutrients from dead or living organisms even jet fuel or wall paint. There are some forms of Ascomycota that produce asexually like Candida Albicans, causing vaginitis in women and Aspergillus flavus, a contaminant of nuts, which is a known carcinogen. Some other commonly known Ascomycota are black truffles and even some edible mushrooms. The yeast portion of Ascomycota produces Saccharomyces cerevisiae, the yeast used to make bread and to ferment beer. Penicillium is also produced from these fungi. Basidiomycota also known as club fungi produces sexually or asexually, known as teleomorphs. From asexual reproduction a portion of the hyphae breaks off and grows a new mycelium forming a vegetative mycelium, if it finds a suitable structure......

All Fungi Are Not the Same

...Microbiology Fungi Essay Not All Fungi Are the Same All fungi are unique in their own way and each represents something new and exciting within the world. As new fungi are discovered and more is becoming known about the existing fungi our knowledge is growing and helping us to live a better life. A few of the fungi studied about are zygomycota, ascomycota, and basidiomycota, which will be discussed in further detail throughout this paper. Zygomycota are also known as “conjugation fungi” and make up only about 1% of known fungi species (Zygomycota). These fungi can reproduce both sexually and asexually; when asexual they spread by a sporangium breaking open and allowing the sporangiospores to spread out, if the spores come in contact with a suitable medium they begin to grow. Zygomycota produce zygospores when they reproduce sexually, this occurs when the nuclei of two cells morphologically similar fuse together. Nutrients are obtained by the fungi by decomposing soil, plant matter, and dung of either animal or fungal origin (Clark, Curtis 2010; Zygomycota). This fungi phylum plays a major role in the carbon cycle because of its ability to decompose items within the environment (Clark, Curtis 2010). Zygomycota are also used to control some insects and can be used for fermentation (Clark, Curtis 2010). Common black bread mold called Rhizopus stolnifer is an example of asexual producing Zygomycota. Approximately 75% of all fungi are ascomycota fungi, also known as......

...their reproduction methods, means of obtaining nutrients, and importance to humans. Be sure to include representative examples of each type of organism in your response. Your essay should be approximately two pages in length, double-spaced in 10 to 12 point font. If you refer to sources of information besides the textbook, please be sure to cite them in the text and on a reference page using APA format. The Zygomycota are also called conjugation fungi. The reproduction is both sexual and asexual spores. The sexual spores are the zygospores which results from the fusion of the nuclei of two cells that are similar to each other. Assexually, the spores are sporangiospores which germinate in to new mold thallus if dispersed into a suitable medium. The Zygomycota hyphae are non septate. Some species act as agents of plant disease and others can lead to opportunistic infections of diabetic and other immune-compromised patients. Examples of Zygomycota include rhizopus, Mucor, Absidia and Circinella. The Ascomycota are also called sac fungi and reproduce sexually through fusion of 2 nuclei that can be similar or dissimilar to create an ascopore which are produced in a saclike structure called ascus. Asexually, the spores are condia or mitospores which are produced in chains from conidiophore. They include molds and some yeast. The Ascomycota are heterotrophs and obtain nutrients from dead or living organisms. They can consume carbonaceous subtrates including jet fuel and wall......

...All Fungi are the Same Jason Tipton Excelsior College Not All Fungi are the Same Fungi have many different characteristics than those of bacteria. Most fungi can live and survive in an environment that can be hostile to most bacteria’s (Tortora,Funke & Case 2013). Even though a fungus is so much different from bacteria, there are many types of fungi that are different from eachother. Some examples of this are the differnces in the three fungi, Zygomycota, Ascomycota, and Basidiomycota. Some of the differences they may have can include: each ones reproduction methods, means of obtaining nutrients, and their importance to humans. Zygomycota is known as an conjunction fungi, and they are saprophytic molds that include an coenocytic hyphae ( Tortora,Funke & Case 2013). There are approximately 1050 species known that are Zygomycota and they are mostlyare found living in soil or on decaying plant. An example of a form of the zygomycota fungi is Rhizopus, which is known as the common black mold found in or on bread. The sexual spore of a zygomycota is called a zygospore, and it is eclosed in a wall and is considered both sexual and asexual. Before germination the spore is in a dormant state. There are two types of dormancy are the exogenous and endogenous. Zygomycota are said to be the most ecologically diverse group of fungi, functioning as saprophytes on substrates such as fruit, soil, and dung( James and O’Donnell 2004). Ascomycota is known as a sac fungi......

Micro Assignment 1

...The three main phyla of fungi are Zgomycota, Ascomycota and Basidiomycota. Three main phyla has there is a forth known as imperfect fungi. Fungi are divided into phyla primarily based on their reproduction structures. Most fungi are adaptable to more extreme environments than bacteria would be able to survive and thrive in. For example most fungi prefer lower pH levels that would be far too acidic for most bacteria. They also have the ability to flourish in low moisture environments, such as many of our foods that are spoiled due to these classifications of organisms. All fungi are chemoheterotophs, meaning they must absorb their nutrients, vice, ingesting it as those in the animal kingdom. They also have the ability to produce enzymes that deteriorate complex carbohydrates for metabolism. These enzymes adhere to the tissue of fruits for example, breaking down the skin of the fruit. Thus the reason, fruits turn dark when they begin to spoil. As stated above, fungi are classified into distinct phyla based upon their reproductive structures. Each phylum will be discussed separately with examples of organisms with in the phyla as well as important aspects associated with humans both positive and negative. Organisms within the phylum Zygomycota have the ability to produce both sexually and asexually. Normally reproduction is carried out asexually until condition become right for sexually reproduction. In the asexual cycle, sporangiospores are contained within......

Identify a mold that produces zygospores.   A thick-walled spore of fungi that is formed by union of two similar sexual cells, usually serves as a resting spore, and produces the sporophytic phase an example is rhizopus. It’s a black mold and grows on old bread and fruits. C. Describe what type of growth you observed in each of your substrates (e.g., number of colonies, shape, color, and defining characteristics). I saw about three different types of fungi on the bread. There was a dark green and white while the cheese only had some green fungi and all the colonies were all attached to each other looking like a sponge. On the strawberry I noticed a whitish-greenish-grey growth also with the hyphae growing outwards. It was all around the strawberry and the colonies was about 3 growing towards each other. On the tomatoes I noticed very a lot of green-bluish and white colonies, I think there is grey also Its all over the tomatoes. The yogurt had a dark grey lump of growth on top of it. It looked like it was floating but it is not. The corn had a white and brown growth. It looked long and stretching down the corn (Gladwin, & Trattler, 2011). D.

...Assignment : Yeast and it’s Phyllum Yeast is naturally growing fungi that grows as a single cell, producing daughter cells either through budding (budding yeast) or by binary fission. They differ from most fungi as most fungi grow as a threadlike hyphae. Yeast is used in baking purpose or fermentation where it helps the dough or the grapes to release carbon dioxide and alcohol. Yeast grows mostly in moist environments where there is a good supply of nutrients such as carbohydrates and amino acids. For this reason they are commonly found on the surface of the leaves and fruit surface or on the tip of the roots. (Deacon) There are many different types of yeast, but the most common ones are the, Saccharomyces also known as the budding yeast which is used in bread making. Cryptococcus species are another type of yeast found commonly on the leaf surface. There are similar yeast, but with different species names are used for the production of alcoholic drinks. (Deacon) Yeast is very harmful to humans and plants equal. One example is the C. neoformans which occurs 7-8 percent of AIDS patients in the USA. The capsule that is exhibited by the yeast can sometimes prevent the cells from being recognized and engulfed by the white blood cells.The C. neoformans grows specially in old bird droppings in the cities. The most common symptoms are lung infection, mild pneumonia, depending on the immunity of the body. The other type of yeast that stays in the mucosal membranes of the humans...

Rumen Fungi

...Rumen Fungi and yeast While they may be considered the smallest microbe in the rumen, approximately only accounting for 8% of the microbial biomass. These microorganisms inhabit the rumen alternating between two forms: a motile flagellated form called the zoospore and a non-motile vegetative form. During zoosporegenesis, the flagellated zoospore is released from a sporangium and under desirable environmental conditions, begins to germinate and further develops into a mycelium and rhizoid. Thus, anaerobic fungi performs very important roles in the digestive system such as carbohydrate fermentation, polysaccharide degradation as well as solubilization of lignin. Firstly, rumen fungi are obligate anaerobes and this gain their energy as well as maintain growth from the fermentation of plant monosaccharides such as fructose, glucose and cellobiose. For example, anaerobic fungi uses the metabolic pathway of glycolysis to convert glucose to pyruvate, which in turn is converted to lactate. This products are then further converted to the major end products; acetate, CO2 and H2. On the other hand, majority of the plant material available in the rumen is in the form of complex structural carbohydrates such as cellulose, hemicellulose, pectin, starch and insulin. The anaerobic fungi is able to degrade these polysaccharides as fungi is able to penetrate the cuticle barrier as well as vascular bundle and attack the strong bonds of these complex carbohydrate residues. This forage is then...
