Cactuses 仙人掌

Cactuses are used to living in desert. The whole body of a cactus is green. The stalk is oval and there are thorns all over its body. Actually the thorns in their bodies are their leaves. The leaves are like this only because they can stop the water in their bodies from evaporating into the hot and dry air. The cactuses have long roots and they take their roots deep into the earth so that they can get the water from deeper,soil.

Their flowers are always small and white.Although they are ignored in the desert, they never give up coming ont and alwaysdecorate the desert silently.
