Question

Some desert plants have very small leaves whereas some other have only spines ? How does this benefit the plants ?

Answer 1

it help to decrease the transpiration process and protect from water lose

Answer 2

Answer:

• Some 'desert plants' have very small leaves or reduced to spines, spikes, or even without leaves in order to adapt themselves to survive in the extremely hot and dry "climatic conditions" of the desert areas.
• This adaptation is to reduce the loss of water through transpiration from leaf surfaces, if the surface area of the leaf is small, then the water loss will also be less.
• The limited leaves also are modified to store water and some are also covered with a "waxy coating" to prevent excessive transpiration.
