transpiration

Question 1

what does the phloem do?

Answer 1

transports food, glucose from leaves to the rest of the plant
transport in both directions
translocation

Question 2

what does the xylem do?

Answer 2

transports water and minerals from the soil up the roots to the rest of the plant
transports upwards
made of dead cells strengthened with lignin

Question 3

what is transpiration?

Answer 3

loss of water through leaves

evaporation and diffusion

Question 4

what do guard cells do?

Answer 4

they open and close the stomata
they close at night and open at day time for photosynthesis
they are most commonly found underneath the leaf so not much water is lost through transpiration during photosynthesis

Question 5

factors affecting transpiration

Answer 5

light intensity
temperature
surface area
humid weather slows down
air flow more wind more loss of water

Question 6

layers of a leaf

Answer 6

waxy cuticle
epidermis
palisade mesophyll
spongy mesophyll
epidermis

Question 7

what does palisade layer do?

Answer 7

contains chloroplasts which contains chlorophyll where photosynthesis can take place

Question 8

function of the waxy cuticle?

Answer 8

protects plant from predators, stops plant from water loss

Question 9

function of spongy mesophyll?

Answer 9

air spaces to allow diffusion of gases

contains xylem and phloem
