Diversity - Fungi

Question 1

fungi

Answer 1

eukaryotic cells surrounded by cellwall made of CHITIN
- has vacuoles
- no chlorophyll = can’t photosynthesize
- multicellular (most)
- heterotrophic

Question 2

4 diff ways of getting energy

Answer 2

1. consume living things - parasitic
2. break down dead/decaying organisms - saprophytes
3. trapping prey - predatory
4. develop partnerships with/ other organisms - mutualism (e.g. chytrid fungi which live in moose guts and help digest the cellulose of plants

Question 3

structure of fungi

Answer 3

• bodies are made of filaments called hyphae
• cells can have 1 or more nuclei
• some hypha are seperated by septum
• mycelium = densely packed hyphae in a branching underground network
• above ground = fruiting body, where spores are formed

Question 4

mycelium

Answer 4

densely packed hyphae, branching underground in a network

Question 5

how fungi feed

Answer 5

-releasing digestive enzymes from hyphae
-break down large organic molecules into smaller ones that can be absorbed = extracellular digestion

Question 6

asexual reproduction of fungi

Answer 6

yeast produces small buds that are identical to parent = budding
small part of mycelium breaks off to form new indivdual = fragmentation

Question 7

sexual reproduction of fungi

Answer 7

• spores
• male and female strains to produce spores, but can grow into a new individual by mitosis

Question 8

types of fungi

Answer 8

• imperfect
• chytrids
• zygospore
• sac
• club

Question 9

Imperfect fungi

Answer 9

deuteromycota

Question 10

chytrids

Answer 10

chytridomycota

Question 11

zygospore

Answer 11

zygomycota

Question 12

sac

Answer 12

ascomycota

Question 13

club

Answer 13

basidiomycota
