They store water inside the shoots,they also have small leaves so they conserve moisture.

well, they do not readily 'adapt'
You can plant watermelons and squash in the desert, they won't 'adapt'
typical desert plants are cacti and certain grass
cacti are more suited for for desert survival
-the cacti have shallowa and wide roots to gather the moisture from th esurface, usually early morning dew
- the cacti store water inside themselves and give up very little through evaporation
- they do not have leaves to grow and replace every year

I leave the rest to you
How do the cacti produce chloroform without leaves?

Yes, they mostly form some kind of channel to direct the morning dew to where it needs it. A lot of plants swell-up with moisture if there's some rain. They have a waxy-like epidermis to avoid evaporation by the sun. Then as others have said, they protect themselves by being spiny inedible and/or poisonous.

Some hold back their flowering period until there is a rainstorm, then they flower, set seed and fruit all in a very short space of time to make best use of the water.

Cacti evolved to store moisture to protect itself from long periods of drought. They also developed spines to discourage animals from biting into their stems to get at the liquid. That's just one example.

They don't need lots of water to survive.
