They vary in size from species to species and my be the size of nails or like small hairs.
Examples of plants that have thorns include roses, cacti, bougainvillea, and blackberries. Thorns are typically used by plants as a defense mechanism against herbivores.
Thorns evolved as a defense mechanism to protect plants from herbivores, reducing the chances of being eaten and increasing their survival. They also help deter animal browsing and provide a physical barrier against potential threats like parasites or pathogens. Over time, plants that developed thorns had a better chance of reproducing and passing on this trait to their offspring, leading to the widespread presence of thorns in many plant species today.
thorns
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.
Plant thorns are sharp, pointed structures that develop from the plant's outer epidermal layer. They serve as a defense mechanism to protect the plant from herbivores and other threats. Thorns can vary in size, shape, and degree of sharpness depending on the plant species.
Blackberry plants have thorns as a defense mechanism to protect themselves from being eaten by animals or humans. The thorns act as a deterrent to predators, helping the plant to survive and reproduce.
