1

you're pretty fly for a

Fungi

2

What is a fungus?

Chemo-organotrophic

eukaryote

that forms spores

3

What are the differences between plant cells and fungal cells?

Fungal cells do not contain chlorophyll - they do not photosynthesise

Fungal cell walls contain ergosterol (this is important in antimicrobial chemo topic) whereas plant cell walls do not

4

What is the cell wall of fungal cells made from?

Chitin or glucan

Which are polysaccharides

5

What are different species of fungi generally classed based on?

Morphology (shape)

6

What are the 3 groups of fungi?

(Not shapes)

(BAZ)

Basidiomycetes - mushrooms

Ascomycetes - yeasts

Zygomycetes - mould

7

Fungi produce two different spores, what are these?

Sexual spore and asexual spore

8

Candida is an important group of fungi that is pathogenic to humans.

What type of fungi is it?

Ascomycete

(yeast)

9

What is the shape/structure of basidiomycetes? (mushroom)

Bullet shape

Basidiospores are outside the cell, attached via sterigmata

2 sections: Basidium + Hypha

Sections separated by the septum

10

What is the shape/structure of ascomycetes? (Yeasts)

Looks a bit like a spaceship

Ascospores contain inside the cell, in an Ascus (sac)

11

Describe the structure/shape of zygomycetes (moulds).

Looks like a TIE fighter from star wars (H shape)

Rough wall

One or more zygospores contained in the centre

12

Describe how reproduction of yeast cells (ascomycetes) through budding works...

Bud begins to form off original yeast cell

Bud grows

Once bud is the same size as the mother cell, it splits off as a new yeast cell

13

Generally, what time frame does budding repeat over for yeast cells?

Usually takes place every 2 hours

14

Why do many fungi species thrive on the skin and nails?

Dermatophyes

Abundance of keratin

Can utilise it as a food source

15

What is the sexual spore of ascomycetes?

Ascospores

16

What is the asexual spore of zygomycetes?

Sporangiospores

17

What is the sexual spore of basidiomycetes?

Basidiospores

18

What is the sexual spore of zygomycetes?

Zygospore

19

What is the asexual spore of ascomycetes?

Conidium

20

What is the asexual spore of basidiomycetes?

Conidium

21

What are important pathogenic species of zygomycetes (moulds)

Mucor

Rhizopus

22

Trichophyton, epidermophyton and microsporum are responsible for causing what?

Athletes foot

These are all types of ascomycetes - yeasts

23

What is Candida responsible for causing?

Thrush

24

What clinically important species of basidiomycetes are there?

Cryptococcus - this causes Cryptococcus neoformans

Malassezia - causes Pityriasis versicolor
