Q.3 Identify the natural habitat of cactus plant. How is a
cactus plant suited to its environment in this habitat?
Answers
Most cacti live in habitats subject to at least some drought. Many live in extremely dry environments.
They are most commonly found in sandy deserts throughout the tropical regions. They can tolerate drought conditions very deftly.
Cacti are photosynthetic just like other plants; they use the sun for energy to grow. The body of a cactus actually swells in times of moisture so that it can store the much needed water for later. In times of drought the body sinks in, or contracts. The most distinct part of a cactus is its spines. Because regular leaves don't conserve water well, the cactus developed these modified leaves to adapt to its extremely dry environment.
They also posses spines which are better at conserving water and surviving in hot temperatures.
