Q

How does the shape of a plant cell differ from that of an animal cell?

A

A plant cell has a cell wall which helps it maintain a rigid structure whereas an animal cell has no cell wall

20
Q

nucleolus

A

found inside the nucleus, in charge of making proteins in the nucleus

21
Q

difference between rough and smooth ER

A

rough ER has ribosomes attached. smooth ER creates lipids needed by the cell

22
Q

why are lysosomes important

A

they are filled with acid enzymes and absorb unwanted substances in the cell and break them down

23
Q

difference between prokaryotic and eukaryotic cells

A

prokaryotic cells have no nucleus circular DNA and no membrance bound organelles (bacteria) whereas eukaryotic cells have a nucleus, linear DNA and membrane bound organelles (animals and humans)

24
Q

respiration key factors

A

happens all the time, occurs in the mitochondria, happens in all cells

25
Q

light dependent stage

A

light energy splits water to form oxygen and hydrogen

26
Q

light independent stage

A

the hydrogn combines with carbon dioxide to form glucose, a simple sugar made up of carbon, hydrogen and oxygen

27
Q

two stages of photosynthesis

A

light dependent stage and light independent stage

28
Q

anaerobic respiration

A

when there is no oxygen available, cells can obtain energy through this process e.g. fermentation (alcohol)

29
Q

lactic acid fementation

A

occurs when oxygen isn’t available. occurs in animals and humans, also has 2 ATP molecules

30
Q

ATP

A

adenosine triphosphate

31
Q

alcohol femenation

A

occurs in yeasts and some bacteria. produces alcohol and carbon dioxide (which is used to form ATP). glucose - pyruvic acid - alcohol + carbon dioxide + water

32
Q

aerobic respiration

A

glucose + oxygen - 36 ATP + carbon dioxide + water

33
Q

where does the light dependent stage occur

A

thylakoid

34
Q

where does the light independent stage occur

A

stroma

35
Q

independant variable

A

what you deliberatly change

36
Q

dependant variable

A

what is measured (CO2)

37
Q

controlled variable

A

what is kept the same (amount of water)

38
Q

which flask has the most carbon dioxide

A

the one with the plastic plant and fish because the fish is breathing out co2 and the plant is fake so it can’t intake the co2

39
Q

which flask has the most oxygen

A

the one with only pond weed because respiration is occuring in the plant meaning oxygen is being made and theres nothing else in the flask to use up the oxygen

40
Q

in aerobic celluar respiration, what three major steps are involved?

A

glycolysis, krebs cycle and electron transport chain

41
Q

glycolysis respiration happens in the what

A

cytoplasm

42
Q

krebs cycle and the electron transport chain occur in the what

A

mitochondria

43
Q

centrioles

A

Centrioles are paired barrel-shaped organelles located in the cytoplasm of animal cells
They play a role in organising microtubules that serve as the cell’s skeletal system.

44
Q

golgi apparatus

A

an organelle found in most eukaryotic cells

packages proteins into membrane-bound vesicles inside the cell before the vesicles are sent to their destination.

45
Q

organelle

A

is a membrane bound structure found within a cell.

46
Q

plant cell

A

eukaryotic cells present in green plants

47
Q

animal cell

A

type of eukaryotic cell that lacks a cell wall. It has a true, membrane-bound nucleus along with other cellular organelles.

48
Q

bacterial cell

A

Bacteria are prokaryotes, lacking well-defined nuclei and membrane-bound organelles, and with chromosomes composed of a single closed DNA circle. They come in many shapes and sizes
