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

16
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
Q

molds definition

A

multicellular fungi grow as hyphae or mycelium

23
Q

mycelium is

A

mass of hyphae

24
Q

caps form

A
    • bag like structure
  1. unmbrella structure
25
stalk
a long cylinder filaments
26
filaments
cells that make up the entire of fungal body , they form dense network together
27
the cells of multicellular ______ into______________called_____
arranged branching threadlike tube hyphae
28
hyphae functions :
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
29
yeast form
compact , creamy , mucoid or pasty colonies
30
yeast example
staphyllococci
31
is the only true yeast which is important to human pathogen
Cryptococcus neoformans
