Q

What is Respiration

A

Respiration is a chemical reaction which occurs in every one of the cells in the human body. It releases energy stored in glucose and without it, these cells would die.

Q

What is produced in anaerobic respiration in humans?

A

they make it sour

51
Q

What does a flagellum do

A

moves the cell

52
Q

what does chromosome do

A

contains the information to control the cell

53
Q

where are protocists found

A

in all habitats

54
Q

What do protocists feed on

A

bacteria

55
Q

Where do protocists mov eon

A

tiny little hairs

56
Q

Can protocists sometimes be green

A

yes because of chloroplasts

57
Q

pseudopods help amoebas move

A

because some dont move

58
Q

How do protocists eat cytoplasm

A

it surrounds it then englufs it

59
Q

how do pseupods move

A

they stretch out from the cell and used to pull the rest of th cell towards them

60
Q

What are pseupods for

A

they help amoebas move and they stretch out their cytoplasm

61
Q

why does algae have an eyespot to detect light

A

so they can produce photosynthesis

62
Q

where does algae get its energy from

A

from the light when they photsyntheies

63
Q

what resources do protocists need to grow well

A

moisture and warmth

64
Q

examples of fungi

A

mushrooms yeast and mould

65
Q

do fungi cells have a nucelus

A

Yes

66
Q

do fungi cells have chloroplasts

A

No

67
Q

What is a ringworm

A

A common skin diease thought to be caused by worms

68
Q

How could of David Gruby discover a fungus in the rings.

A

by a microscope

69
Q

how do yeast reproduce

A

use budding

70
Q

what is budding

A

asexual reproduction

71
Q

what is the product with glucose

A

from the digestive system

72
Q

what is the product of carbon dioxide in anaroebic respiration

A

waste product exhaled (poisonnous)

73
Q

what does aroebic respiration release

A

energy for yeast cells and produces more carbon dioxide

74
Q

why do we add yeast when making bread

A

make it rise

75
Q

what is fermentation

A

when yeast respires anaoerobically and is used to make wine and beer

76
Q

why is air kept out of juice mixture

A

make sure it ferments

77
Q

is yeast part of the fungi kingdom

A

yes

78
Q

is glucose a limiting factor for yeast to grow

A

yes

79
Q

what is chromosomal DNA

A

giant loop of DNA containing most of the genetic material

80
Q

what si the Flagella

A

long whip like sctructure that allow the bacteria to move themselves

81
Q

what is teh slime coat

A

layer surroudning the bacteria cell to protect it from enviromental dangers

82
Q

why does a bacteria cell need a flagellum

A

help it move themselves

83
Q

why does a bacteria cell need a slime coat

A

to protect itself from enviromental dangers

84
Q

does a bacteria cell have nucleus

A

no

85
Q

what is the difference between budding and binary fission

A

Cytoplasmic division

86
Q

what is binary fission

A

a type of asexual reproduction

87
Q

does temperature and glucose effect the growth rate of bacteria

A

Yes

88
Q

what is bacteria

A

a member of a large group of unicellular microorganisms which have cell walls but lack organelles and an organized nucleus, including some that can cause disease.

89
Q

is bacteria unicellular

A

yes

90
Q

What do bacteria divide by when they multiply

A

binary fission

91
Q

why does yeast population stop growing

A

limiting factors

92
Q

what is the equation for photosynthesis

A

Carbon dioxide + Water =( SUNLIGHT) Glucose + Oxygen

93
Q

is photosynthesis the same as areobic respiration

A

No because areobic respiration uses oxygen and produces carbon dioxide and photosynthesis uses carbon dioxide and produces oxygen

94
Q

Why do anmials rely on photosyntheis

A

Photosynthesis is really important for animals, including humans because

without photosynthesis we wouldn’t have food because it converts energy from the sun into chemical energy for the food chains.
photosynthesis keeps the levels of oxygen and carbon dioxide in the atmosphere in balance – without it we would very quickly run out of oxygen.

95
Q

what do plants need for photosynthesis

A

carbon dioxide
water
light

96
Q

what do plants make by photosynthesus

A

glucose (sugar)
oxygen

97
Q

what do chloroplasts contain to make them green

A

chlorophyll

98
Q

What is chlorophyll

A

green pigment, present in all green plants and in cyanobacteria, which is responsible for the absorption of light to provide energy for photosynthesis.

99
Q

Where do plants get carbon dioxide from

A

Plants get carbon dioxide from the air through their leaves, and water from the ground through their roots. Light energy comes from the Sun.

100
Q

what is the role of a phagocyte

A

Engulf and destroy bacteria

101
Q

what is the role of a b-cell

A

Makes infection-fighting proteins called antibodies

102
Q

what is the role of a t cell
