Which of these plants can withstand extreme dryness?

Explanation

The question is asking which plant can survive in very dry conditions. The options are: A) Cactus, B) Raphia palm, C) Triplochiton scleroxylon, and D) Parkie biglobosa. The correct answer is A) Cactus. Cactus plants have adapted to their environment and can survive in extremely dry conditions because they store water in their thick stems. This allows them to survive long periods of drought. Cacti are native to arid regions of North and South America. They have evolved to survive in these harsh environments by developing specialized structures such as spines instead of leaves to reduce water loss through transpiration. While other plants may also have adaptations that allow them to survive in dry environments, the cactus is particularly well-suited to these conditions. For example, Raphia palm is a tropical plant that thrives in wet conditions, Triplochiton scleroxylon is a tree that grows in moist forests, and Parkie biglobosa is a deciduous tree that grows in savannas and woodlands. In summary, the plant that can withstand extreme dryness is the cactus because it has adapted to store water in its thick stem and has other specialized structures that reduce water loss.
