Q

Biodegradation

A

Biodegradation (/.e. biological lysis) is very important and useful process carried out by fungi in which they work as decomposer degrading dead animals in the soil, therefore naturally helping in recycling of all organic

Q

Golgi apparatus

A

is a forms vesicles which fuse with the cell membrane i and release enclosed protein in the surrounding medium

17
Q

plasm membrane

A

composed of glycoproteins , lipids and ergosterol which enclosed the entire protoplasm

18
Q

mitochondria

A
  • respiratory electron transport
  • cytoskeleton containing actin microtubels

hlep in cell membrane functions
role in manitaing cell shape formation

mitotic spindel

19
Q

cell wall

A
  1. complex multilayered structrue outside PM constites 90 % of dry W
  2. chitin is polymer acetyl glucosmine
20
Q

filamentous fungi

A

chitin is biosynthesized at growing tip of hyphae and conrtolled by enzyme called synthetase

21
Q

capsule

A
  1. isolate fungi from the environment
  2. acts as transport medium between outside and cell content
22

mycelium is

A

mass of hyphae

24

    • bag like structure
  1. unmbrella structure
25
Q

stalk

A

a long cylinder filaments

26
Q

filaments

A

cells that make up the entire of fungal body , they form dense network together

27

the cells of multicellular ______ into______________called_____

A

arranged
branching threadlike tube
hyphae

28
Q

hyphae functions :

A
  1. absorbing nutrients from surrounding
  2. have a cytoplasm and few orgaenlles
  3. have nuclei thus have the genetic material of funge locked in hyphae
