Transpiration

Question 1

What is the Definition of Transpiration?

Answer 1

The movement of water through the plant and water loss out of the leaf

Question 2

Why is water loss inevitable?

Answer 2

Water loss is inevitable due to the stomata being open during Photosynthesis

Question 3

Is Transpiration Increased or Decreased in Temperature?

Answer 3

Increased - Increase Kinetic Energy of Molecules

Question 4

Is Transpiration Increased or Decreased in Humidity?

Answer 4

Decreased - When the air is humid then there is more water vapour in it. Less Concentration Gradient

Question 5

Is Transpiration Increased or Decreased in Wind?

Answer 5

Increased - Wind blows water vapour away from the Stomata. Keeping the Concentration Gradient high

Question 6

Is Transpiration Increased or Decreased in Light Intensity?

Answer 6

Increased - Light causes stomata to open. Wider stomata allows faster diffusion of water vapour
