transpiration

Question 1

How can plants reduce
water loss?

Answer 1

Thick waxy cuticle to
prevent water loss

Stomata on the underside of
the leaves so they are not in
direct sunlight.

Wilting, leaves collapse and
hang down reducing the
surface area for evaporation

Stomata close – no
photosynthesis but prevents
water loss.

Question 2

why does sunny weather increase the rate of transpiration?

Answer 2

more photosynthesis,
stomata open for CO2 and
water is lost at the same time.

Question 3

why does windy weather increase the rate of transpiration?

Answer 3

Maintains diffusion
gradient so water moves from
the leaf

Question 4

why does dry weather increase the rate of transpiration?

Answer 4

Maintains diffusion
gradient so water moves from
the leaf

Question 5

why does transpiration increase the rate of transpiration?

Answer 5

Increases
photosynthesis and particles
move faster increasing diffusion rate
