17
Q

stage one of transpiration?

A

ORGAN: root
water moves from soil to root hair cells by osmosis
the large surface area maximises water absorption from soil

18
Q

stage two of transpiration?

A

ORGAN: stem
water moves up stem through the xylem vessel by osmosis​

​

19
Q

stage three of transpiration?

A

ORGAN: leaf
water is evaporated from small holes on bottom surface of leaf (stomata)

20
Q

gas exchange in photosynthesis?

A

CO2 IN
02 OUT

21
Q

gas exchange in respiration (plants)?

A

O2 IN
CO2 OUT

22
Q

desert/dry =

A
  • low water levels
  • low stomata levels per leaf
  • lower rate of evaporation of water
23
Q

moist/humid =

A
  • high water levels
  • high stomata levels per leaf
  • higher rate of evaporation of water
24
Q

what is the function of the upper & lower epidermis?

A

for protection

25
Q

what is the function of the mesophylls?

A

for high levels of photosynthesis

26
Q

what is the function and specialisation of the palisade mesophyll?

A

function: photosynthesis​
specialisation: has a lot of chloroplasts and large surface area

27
Q

what is the function of the spongy mesophyll?

A

some photosynthesis occurs

28
Q

what is the function of the guard cells?

A

controls opening and closing of stomata

29
Q

what is the function of the stomata?

A

where gas exchange occurs during photosynthesis​, also water evaporation

30
Q

what does the vein contain?

A

xylem and the phloem

31
Q

what are the features of leaves?

A
  • large surface area
  • thin
  • thin waxy cuticle
  • thin transparent epidermis
32
Q

what is the function of a large surface area in leaves?

A

to maximise light absorption

33
Q

what is the function of leaves being thin?

A

short distance for carbon dioxide to diffuse into leaf cells

34
Q

what is the function of a thin waxy cuticle?

A

protects the leaves without blocking out light

35
Q

what is the function of a thin transparent epidermis?

A

allows light to reach the palisade mesophyll cells

36
Q

what is the passage of water through the tissues when it enters a plant?

A

root hair -> xylem -> spongy mesophyll

37
Q

what factors decrease the rate of transpiration in plants?

A
  • low temperature
  • high humidity
  • fewer leaves
38
Q

what factors increase the rate of transpiration in plants?

A
  • higher temperature
  • high light intensity
  • wind
39
Q

what are the advantages a plant with less stomata will have?

A
  • less water loss
  • plant wont require as much water
40
Q

what are the features of the xylem?

A
  • lignin
  • hollow
  • no cell contents
  • no end walls
41
Q

suggest an advantage of the chloroplasts being located near the upper surface of the leaf

A

to absorb/capture/trap more light
