We're sure that when you mention the concepts of "plants" and "thorns," the first thing that comes to mind is the cactus. However, while in this case thorns serve as a water-saving method, there are numerous types of thorns, each with its own specific function. If you want to learn more about this natural protection system, don't miss the new post from Deco&Lemon. Take note of this feature!
What do thorns on plants mean in botany?
It's common knowledge that plant thorns are those
sharp-tipped, branched structures with
vascular tissue, resulting in a high content of supporting tissue . This is why they are so rigid compared to other similar structures. Now that we've grasped the concept, the next question arises: why do some plants have thorns and others don't? Imagine for a moment being a plant species living in an arid region, where water is scarce. Although it might rain occasionally, drought is essential for the survival of these plants. In this context,
the production and maintenance of leaves requires a significant amount of water , something many plant species cannot afford. Therefore, through evolution, these common elements
have transformed into thorns .
What types of thorns exist on plants?
Foliar spines. As we mentioned earlier, these originate from the transformation of leaves, as is the case with cacti and those of the genus Berberis.
Radical spines. These arise from a modification of the root, a process resulting from lignification. That is, lignin replaces most of the water in the cell membrane, hardening it and increasing its volume. They are very uncommon.
Cauline spines. These are the spines that arise from the transformation of stems. They are also known as reduced branches.
But what role do the thorns play?
While you might think thorns only serve as protection against predators, their importance goes far beyond that. First, we could highlight their ability to
reduce transpiration . Requiring less water, they lack stomata, the two guard cells in their epidermis that separate gases from the outside. This results in less water loss. Secondly, they also act as a form of
sun protection . Plants completely covered in thorns enjoy more shade. This, of course, depends on the anatomy of the thorns. Last but not least,
they can collect water from rain or dew. The droplets on the thorns are absorbed by the plant's pores, keeping it hydrated. We hope you found our information about thorns helpful.
