Answer:
Explanation:
This is a great question. Most cacti are lacking traditional leaves because they evolved and grow in a hot, dry environment.
Their adaptation is one of survival by storing water as long as possible when it is available. Their extensive root system is very efficient at absorbing water from the soil when it rains.
In a typical leaf, there is a large amount of water loss through the stomatas, which are small openings found throughout the leaf surface. This water loss is called transpiration and warm temperatures accelerate the rate of loss.
