Yes that's true........because cactus are found in desert where temperature are very hot that it is really difficult to survive,....so to much water is taken during the process of transpiration ..so cactus's leaves are modified into spines so that it is reduced..
no mate less water or i should say atmost no water is given out by cactus
as it has thick cuticle
so water cannot escape out of it
now you got it?
Yes thanks
