Fungi Kingdom

Question 1

Describe fungi kingdom (8)

Answer 1

• Majorly multicellular, some unicellular
• Eukaryotic
• Cell wall made of chitin
• Most terrestrial
• Not motile, transported via spores
• Reproduce sexually/asexually
• Heterotrophic
• Parasitic, predatory, decomposer, mutualistic

Question 2

How do fungi eat?

Answer 2

Heterotrophs. Release digestive juices that absorb broken down nutrients
Saprotrophs: dead, decaying matter
Parasites: obtain nutrients from host
Symbionts: mutually benefical
Predatory: carnivorous

Question 3

What is a hyphae

Answer 3

Branch/filament of fungus made of one or more cells

Question 4

What are the 5 parts of a fungus (structure)?

Answer 4

Hyphae
Mycelium
Fruiting body
Sporangium
Spores

Question 5

What is mycelium

Answer 5

Mass of hyphae where metabolism occurs

Question 6

What is the fruiting body?

Answer 6

Structure formed by as/sexual reproduction containing spores

Question 7

What is the sporangium?

Answer 7

Sack at the top of a stalk containing spores

Question 8

What is the spore?

Answer 8

(Sexually) reproductive cell of fungus, capable of growing into fungus if given right conditions

Question 9

Describe asexual reproduction in fungi

Answer 9

Mycelium fragment: piece breaks off and grows elsewhere
Budding: single-cell organisms (ex: yeast)

Question 10

Describe sexual reproduction in fungi

Answer 10

Hyphae (haploids) merge, producing fruiting bodies containing spores. Sporangium buds, haploid spores released and transported in air. Spores lands in an area with the right conditions, grows hyphae and becomes new organism.

Question 11

What are the 4 fungi classifications? What are they based on?

Answer 11

• Method of reproduction, type of fruiting body (where spores come from)
• Club Fungi, Zygospore, Sack, Lichens (symbiotes)

Question 12

Describe Club Fungi

Answer 12

• Produce mushroom structure during sexual reproduction
• Spores produced in mushroom head
• Mushrooms grow where hyphae from different fungus organisms exchange genetic info

Question 13

Describe Zygospore fungi

Answer 13

• Reproduce asexually
• Can reproduce sexually using zygospores IF in bad conditions
  Ex: mold from old food

Question 14

Describe Sac fungi

Answer 14

• Most reproduce sexually
• Develop finger-like sacks called asci during reproduction
  Ex: mildew, yeast
  Yeast reproduce asexually (Budding)

Question 15

Describe lichens (symbiotes)

Answer 15

• Fungi have mutualistic relationship with photosynthetic organisms (algae, cyanobacteria)
• A/C photosynthesize, produce simple sugars as food for fungus
• Fungus creates structure for A/C to live in by creating optimal conditions
