Question

PLEASE HELP!!Explain how the structures that are unique to plant cells help a cactus survive a harsh desert climate

Answer 1

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. The spines are better at conserving water and surviving in hot temperatures. Regular leaves provide a large surface area for evaporation of water to occur, the tiny spines do not. The spines actually collect moisture from the air and let it drip down to the roots of the cactus. Also, spines are used to ward off predators.
