Question

what problem could the cactus plant face if it had leaves like other plants​

Answer 1

Answer:

The desert is a difficult place to be a plant because of the dry, hot air. To move nutrients up their roots, plants evaporate water from their leaves in a process called transpiration. But in the desert, where water is hard to come by, many plants have adaptations to help save water. The plants can save water a few different ways: they can control the amount of water lost by transpiration, the amount they can get, or the amount they can store. If a plant has adaptations to help them deal with desert weather, we call them xerophytes, a word that means dry plants.

Answer 2

Simply, due to open stomata in day time, the water will evaporate and the plant lead to death.
