The desert cactus
The roots absorb water and that makes the stem grow
A cactus can store water in its fleshy stem and this enables it to survive periods of drought.
No, actually the stem of a cactus is adapted to store water. The thick stem allows cacti to survive in dry desert climates by storing water for extended periods of time.
because as we all know, cactus' do not have leafs, and for mot cactus' that live in the desert or suburban areas there is little rain. so the stem of the cactus does the same job as the leaf does on a normal plant and performs photosynthesis.
In most species the stem has evolved to be photosynthetic and succulent,while the leaves have evolved into spines,this helps it adapt to hot and dry environments.
In a cactus the leaves have been reduced to spines, to reduce the surface area from which water can be lost and to deter animals from eating the plant. As there are no leaves, photosynthesis must take place in the stem.
