spores and other fungi strcutures

Question 1

spore and fungi basic

Answer 1

○ Eukaryotic, no chlorophyll
○ Absorb nutrients
○ Exist in both mold and yeast form

Question 2

yeast characteristics

Answer 2

simple
-single cell
-grow best at body temp
-we carry normal flora yeast, not a problem
-identified by assimilation sugars

Question 3

mold characteristics

Answer 3

more complex
-multicellular
-grow best at 30
- no mold in us
-can be contaminant or pathogen
-ID sporulating structures under microscope

Question 4

how is mold transferred

Answer 4

aerosolization
-work under hood
-negative pressure room

Answer 8

fungi imperfecti

Question 9

normally ID what stage of fungi reproduction

Answer 9

asexual

Question 10

sexual reproductive spores found in

Answer 10

nature

not common

Question 11

formed when a nucleus from a male cell passed through a bridge into female cell

Answer 11

ascospore

Question 12

3 reproductive spores

Answer 12

ascospore
basidiospores
zygospores

Question 13

where is ascospore found

Answer 13

sheathed in cleistothecium

Question 14

where do basidiospores emerge

Answer 14

on top of basidium

Question 15

zygospores

Answer 15

2 compatible hyphae each extend an arm toward each other and fuse to form a zygosporangium

Question 16

in asexual spores blastospores are the

Answer 16

budding off the mother cell

-associated with yeast
elongate pseudohyphae

Question 17

arthrospores

Answer 17

asexual
-barrel shaped spores and are simple in structure and nutrition of all spores

-produced at end of hyphal element and break off hyphae - aerosolization

Question 18

where is arthrospores more common

Answer 18

mold

Question 19

chlamydospores

Answer 19

-protective spores and form in conditions not conducive for growth
-large oval to round spores, thick

can be terminal, sessile, intercalary

Question 20

where is chlamydospores found

Answer 20

yeast and mold

Question 21

terminal

Answer 21

end of pseudohyphae or hyphae

Question 22

sessile

Answer 22

sitting on the hyphae

Question 23

intercalary

Answer 23

middle of hyphae or pseudohyphae

Question 24

sporangiospores are found in a sac called

Answer 24

sporangium

-when breaks open all spores released

Question 25

where is the only place you will find sporangiospores

Answer 25

on mold that have aseptate

Question 26

sporangiospores found at top of supporting structure known as

Answer 26

sporangiophore

Question 27

most common spore seen in molds

Answer 27

conidia -if doesn't fit in one of other categories it is this -many shapes and sizes

new name of conidia

Answer 28

aleurospores

Question 29

primary supporting structure that will give rise to conidia

Answer 29

conidiophore -long or short

Question 30

has seperations or cross walls in them

Answer 30

septate hyphae- mold

Question 31

has no separations or cross walls in them

Answer 31

aseptate hyphae

Question 32

pseudohyphae only seen in

Answer 32

yeast -elongation of blastospores

Question 33

aerial hyphae

Answer 33

○ Normally where spores are located and can be seen above media (air)

Question 34

vegetative hyphae

Answer 34

○ Will be supporting or nutrient drawing hyphae and will submerged below media - Used as an anchor

Question 35

name given to the mat of hyphae that you see when you look at mold with naked eye

Answer 35

mycelium -lots of hyphae together

Question 36

rhizoids

Answer 36

root like structures whose only functions is to help anchor the fungus to supporting media -does not draw up nutrients -nodal or internodal

Question 37

where is rhizoids seen

Answer 37

aseptate hyphae

Question 38

nodal

Answer 38

right under sporangiophore

Question 39

internodally

Answer 39

between sporangiophore
