That answer is wrong! the roots are just bellow the survice so to soak up as mmuch water as possible when it rains, also they have spikes on their leaves to warn off other prediators not to eeat it. they have thick waxy skin aswell.
all this i know for an absolute fact.
== == Cacti are adapted to living in desert and they can store lots of water. They have spikes to protect themselves from predators. Cacti are adapted to the desert as that is where they grow and therefore they need special features to live in that environment. Over time the cacti has adapted to hot, desert conditions which means that they can live in the desert without needing lots of water.
A cactus has a few adaptations to heat. These include having spikes to keep away organisms who need water, and being able to hold large amounts of water.
they can adapt with the help of thir spines.
cacti can store up to 3 gallons of water and only need a 17th of water that a human needs. they also have those spines to reach and grab water in the air. Therefore making it easy to live.
becar many yuse cactus survive in low water also and they can survive without water for many years
Leaves have evolved into spines on the cactus.
By evolution
no,there would be little change because the cactus wont be able to adapt to the environment.
They grow in clumps so if it is cold they are warm and if it is warm it still stays warm. :)
In a desert, they adapt so that they are able to hold in and store more water. For example, there is a cactus.
