Detailed explanation-1: -Tropical forest cacti (also called jungle cacti) typically originate as epiphytes or lithophytes, growing in a pocket of moss or debris in the crook of a tree branch or a rock. So despite the humid, tropical conditions of their native habitats, these cacti are adapted to grow in a media that is prone to dryness.

Detailed explanation-2: -A cactus has special adaptations in its roots, leaves as well as stems that enable it to thrive in desert environments. These adaptations include: Leaves are reduced to spines to reduce water loss through transpiration. Wide and deep roots absorb rainwater on the surface and reach the underground deep water.

Detailed explanation-3: -Can a cactus grow in any climate? Cactus plants can grow in any climate, although they are native to North and South America. The majority of cactuses are found in the hottest, driest areas on Earth. However, certain species of cacti grow in rain forests, on mountain ranges, and even in Alaska and parts of Antarctica.

Detailed explanation-4: -Water is truly a precious resource in a desert, so, in addition to their intimidating spines, most cactus species further protect their spongy flesh with acids and potent alkaloids. These chemicals are usually too acrid for most humans to tolerate and are taxing on the kidneys if ingested.
