Fungi and Protozoa Flashcards
What are the two major groups?
Filamentous fungi and yeasts
What is the cell wall composed of?
Polysaccharides
- Mannan
- Glucan
- Chitin
What are the two types of fungi nutrition?
Heterotroph: eat organic/other organisms
Saprotrophic: eat dead/decay matter
True or false: Fungi reproduction is only asexual
False: Can be sexual and asexual
What are filamentous fungi?
Cells are filamentous, grown by extension
Moulds
What are the two types of hyphae?
Aseptate: one long tube with cells
Septate: split into individual cells
Explain fungi differentiation
Mycelial differentiate into vegetative and reproductive type
Spores produced
What are yeasts?
Divide by budding
Can revert from yeast to mould
What are the fungal groups?
Zygomycota - bread moulds
Ascomycota - yeast
Basidiomycota - mushrooms
Explain fungal diseases (mycoses)
Skin infection - athletes’ foot
Thrush - infection of mucous membranes
Air, earth borne
What are the uses of fungi?
Mycoprotein used for food, fermentation
What are protozoa?
Motile, non-photosynthetic
Heterotrophic nutrition
Cell wall
True or false: Protozoa reproduction is asexual and sexual
True: it is both
What are the major features of protozoa?
Motility and heterotrophic metabolism
What do pathogenic protozoa do?
Have virulence factors to enhance their infectivity
