31. cacti are plants that live in extremely dry environments. unlike most other plants, cacti do not
have regular leaves, but instead have spines. they do have green stems. how would the lack of
regular leaves cacti survive in their environment? in what part of the cacti would photosyn-
thesis occur?

Due to the cactus storing water within itself, the spines act as a protective bodyguard against the nerds trying to take the water.

The correct answer is "in the thick stems of cacti".

Explanation:

Since cacti are plants do not have regular leaves, the cacti perform photosynthesis in the thick stems of its body. The stems of the cacti are green-colored, and have chloroplasts that are able to perform photosynthesis. In consequence, cacti have adapted to no require leaves to execute photosynthesis, and the stems help them to preserve moisture and tolerate high temperatures.
