19
Q

fungi classification (according to structure) ?

A

1.yeast
2. mold or filamentous fungi
3. dimorphic (have yeast and filamentous fungi)

20
Q

yeasts are uni or multicellular?

A

unicellular

21
Q

yeast size ?

A

3-15 mm

22
Q

yeast reproduce ?

A

asexually by budding to form blastoconidia

23
Q

definition of blastoconidia?

A

An asexual conidium that forms by a blowing out or budding process
ex : yeast

24
Q

pseudohyphe ?

A

elongation of blastoconidia

25
Q

what is an example of blastoconidia ?

A

yeasts such as : C albicans and Cryptococcus neoformans

26
Q

Pseudohyphae

A

resemble elongated yeast cells that remain attached to one another

27
Q

a few pathogenic yeast form capsule
(emalple ) ?

A

Cryptococcus neoformans

28
Q

moulds are ?

A

multicellular

29
Q

( TRUE OR FALSE)
moulds forms hyphe

A

True

30
Q

Hyphe are

A

long, branching, filamentous structure of a fungus

31
Q

(TRUE OR FALSE )

Hyphae are the tubular projections of multicellular fungi that form a filamentous network (mycelium )

A

True

32
Q

mycelium are ?

A

mass of branching intertwind hyphe

33
Q

the types of hyphe of many pathogenic moulds are ?

A

septate
aseptate

34
Q

define septate and aseptate hyphe ?

A

septate : divided into cells by septa .
aseptate : without septa (ceocnocytic hyphhe) feature of zygomycetes .

35
Q

ceocnocytic hyphe

A

Hyphae without septae (Aseptate hyphe)

36
Q

mycelium types :

A

1.aerial mycelium
2. vegetative mycelium

37
Q

what is the difference between vegetative and aerial mycelia?

A

The portion of the mycelium that anchors the mold and absorbs nutrients is called the vegetative mycelium ; the portion that produces asexual reproductive spores is termed the aerial mycelium.

38
Q

sporangiospore

A

The asexual propagules that form inside a sporangium, which can be mostly spherical or cylindrical, through a process involving cleavage of the cytoplasm

39
Q

rhizoids

A

root like structure

40
Q

rhizoids located at ?

A

base of sporangiospore
or along the hyphe

41
Q

dimorphism ?

A

Fungi that have the ability to exist in two forms depending on growth conditions.

42
Q

dimohic shape of fungi
( according to temperature?)

A

Yeast /tissue phase – grows best at 37°C .
Mould phase – grows best at room temperature or 30°C

43
Q

positive effect of fungi

A

Industrial uses of fungi :
-Natural food supply for wild animals.
-
Yeast as food supplement.

-Supplies vitamins.
- Fungi used to alter texture, improve flavor of natural and processed foods.

44
Q

negative effect of fungi

A

1 -plant pathology .
2-human pathogens.
3- immunosuppressed patients increased ability to have fungal infections.
