Which of these is an adaptation of hydrophytes?

• Stomata on underside of leaves
• Stomata on upper side of leaves
• Stomata in rolled leaves
• Stomata shielded by hairs

Transpiration is

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