hydrophyte

What is a hydrophyte

Aquatic pants adapted to water

Why are guard cells inactive

Lots of stomata on upper epidermis

Stomata usually open - no risk of of losing water

Why are thee large air spaces

Makes boyant (more likely to float onto of water)

Allows oxygen and co2 gas exchange in photosynthesis

Why are there flat leaves

Spread across surface. Of water to capture as much light as possible

Why are there small rooors

Water can diffuse directly into stem and leaves

What are some examples of hydrophyte

Water Lilly

Hydrilla

What are some adaptions of water Lillies

Floating leaves (Maximise surface area for P.S while floating on water surface)

Waxy cuticle

Stomata on top - breath air not water

Flexible and hollow - withstand water currents and changes in water level

Hollow to allow oxygen to travel from leaves down to rots

Wide flat leaves - capture as much light
