is the xylem made of dead or living cells?
what do these form?

dead
a hollow tube

1 of 8

what is translocation?

the movement of dissolved sugar through the phloem

2 of 8

what is transpiration?

movement of water through the xylem

3 of 8

give the four steps of transpiration

- water enters roots by osmosis
- travels up stem in xylem vessel
- evaporates from leaf stomata
- pulls water up from xylem

4 of 8

what direction does water and dissolved sugar travel around a plant

water = from roots to leaves
sugar = from leaves, up and down plant

5 of 8

what does the xylem transport?

water and mineral ions

6 of 8

what are the plates in phloem called?

sieve plates

7 of 8

how do
temperature
wind
humidity
light
affect transpiration?

temp = increases. makes evaporation faster, so water pulled up stem at higher rate
wind = increases. water molecules moved from leaf faster, so higher conc gradient
hum = decrease. lower conc gradient
light = increases. more photosynthesis, so more CO2 ne
