Why do desert plan have thorns?

Answer 1

it is their evolutionary defense against attackers.

In a desert environment, water is very scarce. Therefore, every small amount of water absorbed by plants is indispensable to plant survival. The purpose of thorns is to protect the fleshy stems (which contain water) of the cactus from predators.

Answer 2

Thorns are woody protrusions on plants that often have a sharp point. Not all plants have thorns, however, leading some people to wonder why some plants that have little else in common have thorns while similar plants do not. There are several reasons why plants develop thorns, though their development depends on the environment in which the species grows.

Answer 3

the thorns are actually their leaves. They are small so there is less surface area to lose water from through transpiration.
caucuses have thorns so insects that eat that sort of plant or people who want caucuses get poked and the little creatures die on them. if you look closely at a cactus in the desert its likely to have lots of insects on the thorns, therefore caucuses have thorns to protect it and prevent others from touching it

Answer 4

Desert plants have thorns as a defense mechanism against animals that might eat them or against the harsh conditions of the desert environment. Thorns help reduce water loss by acting as a barrier to prevent excess transpiration and protect the plant from herbivores.

Answer 5

To protect the fleshy part from the herbivores

Answer 6

It is nature's way to protect these plants from animals eating them. That way, the plants can remain in the ecosystem and protect against erosion.

Answer 7

Thorns is a way plants protect themselves. They can also be a source of shade and water conservation for some cactus.
