Q

what is the process of photosynthesis

A

the roots pbsorbe water and send it to the plant leaves

carbon dioxide from the atmosphere is obsorbed through pours called stomata

both these and sunlight from outside the plant are observed by the chlorophyll and transformed into glucose and oxygen.

the oxygen is then released back into the atmosphere through the stomata

Q

what is ANerobic respiration

A

when there s no oxygen present and cells can obtain energy

eg fermentation

20
Q

what is erotic respiration

A

then there is oxygen present so the cells can obtain it

21
Q

what is lactic acid fermentation

how much ATP

A

it is when there is no oxygen present

only occurs in animals and has 2ATP

22
Q

what is alcohol fermentation

A

when the yeast used respires and makes a bacteria which makes it alcoholic

23
Q

what is the respiration equation

A

glucose + oxygen => 36 ATP + water + carbon dioxide

24
Q

what are the holes / valves in which carbon dioxide and oxyen come and leave from called

A

stomata

25
Q

name the two parts in the stem of a plant

A

xylem

phloem

26
Q

what process in a plant cells is endothermic

A

photosynthesis

27
Q

which process in a plant cell is enctothermic

A

respiration

28
Q

where does the light dependant stage occur

A

in the thylakoids

29
Q

where does the light inderpendant stage happen

A

in the stroma

30
Q

what are the three steps involved in the aerobic respiration

g
kc
etc

A

glycolosus
kerbs cycle
electron transport chain

31
Q

what is a eukaryote cell

A

they have a:
nucleus
membrane bound organelles
and linea DNA

32
Q

what are prokaryotes cells

A

cells that have :
a nucleoid
a circular DNA

33
Q

function of the cell membrane

A

a layer of protein that lets substances and unwanted shit to flow in and out and it also protects the cell from bacteria infections

34
Q

function of the cell wall

A

a ridged fibre wall that supports the structure of the cell while protecting it

35
Q

function is centrosome

A

located near the nucleus and moves the two parts of the cell to the opposite side during cell decision

36
Q

function of chloroplast

A

an organell containi g chlorophyll that is necessary for the process of photosynthesis

37
Q

function of cytoplasm

A

a jelly like substance that contains all the cells organelles accept from the neucleus

38
Q

function of the golgi body

A

packages proteins and carbohydrates

looks like a stack of pancakes

39
Q

function of the mitochondrion

A

converts energy stored in glucose into ATP

also has a double membrane

40
Q

the function of the nuclear membrane

A

membrane that surrounds the nucleus

41
Q

functions of the nucleolus

A

where the ribosomes RNA is produced

42
Q

function of the nucleus

A

controlla the functioning of the cell and contains all the cells DNA in chromosomes

43
Q

function of the ribosomes

A

small cytoplasmic granules that are made of proteins

44
Q

function of the rough ER

A

is covered in ribosomes

and sends protiens to the golgi body

45
Q

function of the smooth ER

A

it contains enzymes and produces lipids

moves these to the golgi body

46
Q

function of the vacuole

A

contains all the nutrients and fluids (water) in the cell
