Desert Cacti

Desert Cacti

Cacti show many adaptations to living in desert regions where every drop of water has to be conserved. The roots of cacti may spread over a wide area to absorb as much water as possible after a rainstorm or the roots may be thickened to store available water. The stems are thick and succulent and they are coated with a waxy substance to help prevent water loss. [CH] {CA}
