Why do cacti have spines?
Cactus, that spikey plant which lives in arid deserts. But they don't have leaves. They have spines instead. Why? Let's see.
Spines help cacti to reduce transpiration. Transpiration is the loss of water from ariel parts, like stems and leaves, in the form of water vapor. These ariel parts contain stomata which allow water vapor to escape into the atmosphere.
In deserts, where cactus usually grows, there is scarcity of water. Also, due to high temperatures, the rate of transpiration is very high. Thus, the leaves of a cactus have modified into spines. Thus, the rate of transpiration is reduced, helping the cactus to save water.
Moreover, animals in deserts try to find water. Having spines, will protect cacti from being the food of animals and humans like Bear Grylls ofcourse!

I thought it would be better not to delete or revamp these posts, even if they suck. The bitter truth is that old works always suck, but I take that as a positive tool to convey that I am growing. Besides there's no better way to showcase my journey without these old, messy, poorly written posts!
