Question

True or false: Guard cells close openings in the leaves slowing down water loss.

Answer 1

Answer:

True

Explanation:

Stomata are pores in the leaf that allow gas exchange where water vapor leaves the plant and carbon dioxide enters. Special cells called guard cells control each pore's opening or closing. When stomata are open, transpiration rates increase; when they are closed, transpiration rates decrease. So when it is opened the water vapor depletes quicker but when its closed it slows down the process of depletion.

True

Guard cells close openings in the leaves slowing down water loss.
