Factors affecting transpiration in plants

Question 1

factors that increase stomatal opening will increase rate of transpiration including

Answer 1

temp, humidity, air flow and light intensity

Question 2

adaptations that help plants to photosynthesise as much as possible without losing much water

Answer 2

waxy cuticle, stomata on underside of leaf, wilting (reducing surface area)

Question 3

why are transpiration rates higher at greater temperatures

Answer 3

evaporation is faster

Question 4

why are transpiration rates higher at dry conditions

Answer 4

evaporation is faster

Question 5

why are transpiration rates slower at humid conditions

Answer 5

reduces conc. of water molecules outside leaf

Question 6

why are transpiration rates higher at windy conditions

Answer 6

removes any water vapour from leaf surface allowing more water to evap.

Question 7

why are transpiration rates higher at hight light intensity

Answer 7

increases rate of photosynthesis and stomata opens to let c02 enter
