LAB REPORT FUNGI Name: 1. Identify the characteristics of the Kingdom Fungi. 2. List the class characteristics for the following. A. Phylum chitridiomycota_ B. Phylum zygomycota _ C. Phylum Ascomycota _ A. Phylum Basidiomycota _ D. Phylum Glomeromycota. B. Former Phylum Deuteromycota _ 3. Describe the mutualistic symbiotic association that produces lichens and mycorrhizae. Explain the role of the symbionts in each association _ 4. Define: 1. Sporangium 2. Coenocytic 3. Hypha 4. Spore _ 5. Zygospore

Explanation / Answer

1.
non-vascular organisms
reproduction by spore
non motile
heterotrophic
nuclei is small
nuclear envelope is not dissolved during mitosis
Reproduction - sexual and asexual

2.

a) chytrimycota
chitin in their cell walls
most are unicellular; a few form are multicellular and hyphae,
reproduction - sexually and asexually
gametes are the only fungal cells
live in aquatic environments,except some

b) zygomycota
cell walls containing chitin
most Zygomycota form hyphae
asexual reproduction

c) ascomycota
cell walls made of of chitin and beta glucans proportions
can be a single celllike yeasts or a long tubular filament

d) basidiomycota
unicellular or multicellular
Reproduction - sexual or asexual
terrestrial or aquatic

e) glomerocyta
obligate symbionts
ormation of arbuscules in plant roots
large, multinucleate spores with layered walls
non-septate hyphae

f) deutromycota
Reproduction :asexual
Vegetative hyphae
Cell walls : chitin and glucan

3.
both memebers of the asscociation benefit for human , one classcial mutulaistic asscoication is that of the lactic acid bacteria that lives on vaginal epithelium of women . the bacteria are provided habitat with a constant temperature & supply of nutrients in exchange for the production of lactic acid which protects vagina from colonization .

4
sporangium : is an envelop or enclosure in which formation of spores occurs.

coenocytic : is a multinucleate cell which is formed from multiple nuclear divisions without their accompanying cytokinesis

hypha : collectively called a mycelium are the main mode of vegetative growth

spore : a haploid reproductive cell that give rise to gamtephyte

zygospore : ?its a  diploid reproductive stage of fungi and protists in their life cycle
