Q

how does rhizopus digest the food

A

30
Q
  1. what forms the gametangia
A

the tips are cut off by a crosswall which forms a gametangia

31
Q
  1. what happens to the walls of the gametangia
A

the walls between the gametangia break down

32
Q
  1. when does fertilisation occur
A

when nuclei fuse forming a zygote

33
Q
  1. what develops around the zygote and what does it form
A

a thick wall develops around the zygote forming the zygospore

34
Q
  1. what is a zygospore
A

a dormant, resistant spore

35
Q
  1. when and how does the zygospore divide
A

when conditions are suitable the zygospore divides by meiosis

36
Q
  1. what is formed when the zygospore divides by mitosis
A

a hypha and a sporangium

37
Q
  1. what does the sporangium form
A

haploid spores

38
Q
  1. spores are released to
A

to form new mycelia

39
Q

2 properties of yeast

A

unicellular and saprophytic

40
Q

5 organelles in yeast

A 
cell wall
cell membrane 
storage granules
vacuole
nucleus
41
Q

how does yeast reproduce?

A

asexually by budding

42
Q

first thing that happens when yeast reproduces

A

the parent cell forms an outgrowth or bud that fills with cytoplasm

43
Q

how does yeasts nucleus divide

A

by mitosis

44
Q

what happens to the nucleus

A

moves into the bud

45
Q

what happens to the bud

A

it is cut off from the parent cell forming a new daughter cell

46
Q

what happens once the daughter cells separate

A

rapid budding can produce a small group (colony) of attached cells

47
Q

3 beneficial economic importances of fungi

A

produce antibiotics eg.penecillin
alcohol fermentation by yeast
food - bread or mushrooms

48
Q

4 harms of fungi

A

human disease eg. athletes foot
plant disease eg.potato blight
food decay eg.rhizopus on bread

49
Q

3 edible mushrooms

A

field mushrooms
truffles
oyster mushrooms

50
Q

2 poisonous mushrooms

death caps

destroying angel

51
Q

where can you culture microorganisms

A

52
Q

what are nutrient agar plates

A

dishes with food

53
Q

agar

A

a jelly-like substance extracted from seaweed

54
Q

what does the nutrient used depend on?

A

on the microorganisms being cultured

55
Q

asepsis

A

free of pathogens

56
Q

how do you sterilise

A

in the autoclave

57
Q

autoclave

how do you sterilise instruments

A

flaming them

59
Q

safety precautions

hands

A

wash with disinfectant before and after

60
Q

safety precautions

work bench

A

swab down with disinifectant

61
Q

safety precautions

instruments and glassware

A

sterilise before and after use

62
Q

safety precautions

nutrient growth medium

A

sterilise the nutrient growth medium

63
Q

safety precautions

plates with cultures in them

A

seal the plates

64
Q

To investigate the growth of leaf yeast using malt agar plates and controls
control

A

unopened plate

65
Q

To investigate the growth of leaf yeast using malt agar plates and controls
purpose of a control

A

to show that the yeast came from the leaf

66
Q

To investigate the growth of leaf yeast using malt agar plates and controls
which leaves

A

ash leaves

67
Q

To investigate the growth of leaf yeast using malt agar plates and controls
which agar

A

prepare sterile malt agar plates

68
Q

To investigate the growth of leaf yeast using malt agar plates and controls
how do you attach the leaf discs to the play

A

attach with sterile forceps with vaseline

69
Q

To investigate the growth of leaf yeast using malt agar plates and controls
what do you label the experiments

A

experiment and control

70
Q

To investigate the growth of leaf yeast using malt agar plates and controls
for 24h

A

the this plate the right way up

71
Q

To investigate the growth of leaf yeast using malt agar plates and controls
why leave the right way up for 24h

A

so that the yeast spores from the leaf discs can fall onto the agar

72
Q

To investigate the growth of leaf yeast using malt agar plates and controls
3 days

A

incubate both upside down for 3 days at 25ºC

73
Q

To investigate the growth of leaf yeast using malt agar plates and controls
how do you see the leaf yeast colonies

A

shiny pink spotes

74
Q

To investigate the growth of leaf yeast using malt agar plates and controls
after the experiment 2

A

set up replicates and sterilise the plates to destroy cultures before disposal
