|
It is growing in an environment where the water is dirty so it has to save the clean water
|
|
|
It is growing in an arid environment and needs to conserve what water it can
|
|
|
It is growing in a wet environment and need to weigh down its roots for anchorage
|
|
|
It is dealing with herbivores trying to eat it’s leafy parts and needs water to grown back its stem and leaves
|
Detailed explanation-1: -Plants can require conservation of water if they live in environments which are humid and lacking in a sufficient supply of water. Thus, by conserving their water and reducing their loss, the plants can survive better in those climates.
Detailed explanation-2: -Plants will absorb water through their roots and release water as vapor into the air through these stomata. To survive in drought conditions, plants need to decrease transpiration to limit their water loss. Some plants that live in dry conditions have evolved to have smaller leaves and therefore fewer stomata.
Detailed explanation-3: -∙Leaves are modified into spines to minimize the loss of water through transpiration. ∙The stem has a thick cuticle and huge water holding capacity. The thick cuticle helps in reducing transpiration. ∙Deep roots help in obtaining water from long distances.
Detailed explanation-4: -Stomata – Guard cells surrounds the stomata causing a doorway effect, which could be increasing (swollen) or decreasing (shrunken) in size. Leaf hair – It deflects some light and maintains a cool plant temperature causing minimal loss of water. More items
