Process of Transpiration

Question 1

How does transpiration begin?

Answer 1

• Where water that evaporates from the surface of cells inside a leaf moves out of the leaf by diffusion when the stomata are open

Question 2

By being open, what does the stomata do?

Answer 2

• It maintains a concentration gradient so more water evaporates and diffuses out of the leaf

Question 3

What is the final part of the process?

Answer 3

• The loss of water from the leaf pulls water and dissolved mineral salts up through the xylem from the roots
