|
|
|
water lilies have more stomata on the bottom of their leaves as water loss is negligible.
|
|
|
gum trees’ hanging leaves reduces water loss
|
|
|
leaves with stomata in pits are usually found in rain forests
|
|
|
Plants with short life cycles are suited to areas with good rainfall

Detailed explanation-1: -Plants adapt to their environment from necessity. Plants may also adapt by growing lower and closer to the ground to shield themselves from wind and cold. Desert environments may have some of the following adaptations, these help the plant to conserve food, energy and water and still be able to reproduce effectively.
Detailed explanation-2: -Adaptations to Reduce Water Loss Leaves are sometimes reduced to spines. The thick cuticle on leaves reduces water loss. Some plants have stomata only on the lower side. Some of the plants have sunken stomata to reduce water loss.
Detailed explanation-3: -Stomata – Guard cells surrounds the stomata causing a doorway effect, which could be increasing (swollen) or decreasing (shrunken) in size. When the guard cells are swollen, stomata is sealed causing less water loss through transpiration.
Detailed explanation-4: -It creates a microclimate around the leaf. As water is lost from the leaf the microclimate becomes very humid. The hairs prevent this humid air from being blown away. As humidity slows down the rate of transpiration the leaf conserves water.
