• osmosis

• transpiration

• active transport

Water vapour lost from the surface of the leaves through...

• the stomata

• the epidermis

• the palisade cells

• the spongy mesophyll

Transpiration is...

• the movement of water through a plant from the roots up the stem

• the loss of water in the form of water vapour from the surface of the leaves of a plant by the process of evaporation

• the flow of water into plant roots by osmosis from the soil

• the process of minerals and sugars moving through plant veins

Why is the evaporation of water from leaves important?

• It cools leaves and helps move water up the plant.
• It makes the plant wilt
• It helps the plant to respire
