When we think of a cactus plant, the first thing that comes to our mind is its spines, which are nothing but its leaves. The leaves grow from these specialized structures called the areoles. The size of the spines can vary from species to species and they can be as long as 15 cm. As the leaves are small, they prevent loss of water through transpiration. Some cactus spines are light in color which help them to reflect maximum sunlight and keep the plant cool. Another function of the spines is to protect the plant from birds and animals. They actually eat cactus only for water.

These plants have an extensively complicated root system which enables them to absorb water from the soil. Strangely, even small-sized cactus plants have big roots. These roots are not very deep and may not extend beyond 10 cm below the surface of the ground. However, they often spread to wide areas covering almost 2 meters in diameter. The function of the roots is to anchor the plant well, and obtain maximum underground water and minerals.
