Fungus

Question 1

Fungi characteristics

Answer 1

Eukaryotes
Heterotrophs
Haploid
Chitin in cell walls
Most decomposers
Non motile
Most multicellular
Grow best in moist land habitats
Can tolerate various temp, ph and salt/sugar presence
Can have sexual or asexual reproduction (through mitosis)

Question 2

Nutrition

Answer 2

Secrete exoenzymes, digest then absorb
Decompos dead organic material
Main storage is glycogen

Question 3

2 types of fungi

Answer 3

Yeast: round, most unicellular , asexual reproduction, sometimes sexual by releasing 1n spores
Molds, multicellular (most are)

Question 4

Hyphae

Answer 4

Spore germinates ten undergoes mitosis, forms a multicellular hypha, caused by mitosis of haploid cell

Can branch to form mycelium
To obtain nutrients and infiltrate organic matter
Mostly underground,

Can branch to form sporangia or fruiting bodies
Sporangia: structures where spores are made (spores: non motile, wind water or animal dispersion)
Fruiting bodies: sexual reproduction, also makes spores but through meiosis

Question 5

Reproduction

Answer 5

Asexual reproduction through mitosis, sometimes sexual, which through meiosis produces genetically distinct spores (1n) that are released from sporangia
Through spores

Question 6

Eco importance of fungus

Answer 6

Major Decomposers, can use their hyphae to penetrate larger pieces of organic matter, while bacteria ar to what is exposed
Mutualisation relationships, sometimes parasitic
Sources of medicine, antibiotics
Food and drinks (yeast)
