Answer 2

Explanation:

Cactus and acacia are found in forests and have particular modifications in their structure which make them able to live in a hot and dry environment. Such factors include:

a) The thick cuticles which are present on the leaf also the stomata of these plants have a deep pit-like structure which reduces the loss of water from the plant by transpiration.

b) These plants possess a special photosynthetic pathway where the stomata remain closed during day time resulting in the reduction of loss of water.

c) The flattened leaves are not visible in these plants. Instead, their plats are spine shaped to reduce the loss of water. Hence, photosynthesis takes place through the stems.
