factors affecting transpiration

Question 1

factors that increase the rate of photosynthesis or increase stomatal opening will…

Answer 1

increase the rate of transpiration eg temperature, humidity, air movement, light intensity

Question 2

what conditions is transpiration more rapid in?

Answer 2

hot, dry, windy or bright conditions

Question 3

temperature increase

Answer 3

Increases molecular movement so: more water molecules evaporate from cell surfaces; the rate of diffusion of water molecules from the leaf is increased

Question 4

humidity decrease

Answer 4

Reduces concentration of water molecules outside leaf; diffusion of water from the leaf increases

Question 5

air movement increase

Answer 5

Removes water vapour from leaf surfaces; more water diffuses from the leaf

Question 6

light intensity increase

Answer 6

Increases rate of photosynthesis; stomata open so that water diffuses out of the leaf
