plant adaptations

Question 1

how are hydrophytes adapted to their environment

Answer 1

stomata only on upper surface of leaf to allow for diffusion of gasses as if it was on the lower surface of the leaf the stomata would be submerged

air spaces for flotation (bouyancy)

leaves have large surface area to float

submerged leaves are divided to provide large surface area for photosynthesis

Question 2

how are xerophytes adapted to their function

Answer 2

thick waxy cuticle to cut down water loss (reduces evaporation rate and reflects the heat to lower the temp)

sunken stomata further reduces water loss by evaporation

small leaves to reduce surface area and evaporating surface

shallow roots to allow for fast absorption of water
