Step-by-step explanation:
a rainforest plant will have a great number of large green leaves in order to capture the most amount of sunlight that is able to pass through to the lower levels in the rainforest. Also due to the humidity and low wind speed there isn't a high rate of transpiration.
whereas a desert plant where there is high temperatures, low humidity and high wind speed, plants such as cacti have torn as leaves which blocks the stomata in most cases to prevent water loss and to ward off predators, the cacti has roots that allow it to absorb water before it can evaporate
