Defense
Thorns deter herbivores from eating plants by making them difficult to chew and swallow. They can also cause injury to the mouth, throat, and stomach of animals that try to eat them. Thorns are especially effective against large herbivores, such as deer and cattle, which are more likely to be deterred by sharp objects.
Growth
Thorns can also help plants to grow by supporting their stems and leaves. They can also help to protect plants from damage caused by wind and rain. In some cases, thorns can even help plants to climb by providing them with a way to attach to other objects.
Thorns are an important adaptation for many plants. They help them to survive by deterring herbivores and supporting their growth.
