In nature, we can find various plants with spikes or thorny shrubs, which are present for several reasons. One of the causes that explain its appearance -perhaps the best known- is protection. That is, those plants that have spikes are because these spines act as a protective mechanism to deal with threats from animals-eat leaves or fruits or other plants.
But, in addition, there are other factors. And the spikes also prevent the evaporation of water. In this way, it is common for thorns to be present in climbing plants, shrubs, cacti or carpet.
In other plants, the reason for their appearance is much simpler. And they simply replace the sheets with that paper to help maintain moisture. In this way, plants with spikes and spiny shrubs are more common in desert areas, whether hot or cold.
The thorns also have another mission in the plant: they serve as refuge or hiding place for insects or small animals that, otherwise, would be easily devoured.
