Final answer:
Plants in dry regions have adaptations to tolerate or store water. Adaptations include deep root systems, short life cycles, and minimizing water loss. In some arid regions, farmers use extensive irrigation systems to grow crops.
Step-by-step explanation:
Plants that live in dry regions have evolved adaptations to survive and grow in environments with limited water. These plants, called xerophytes, have various strategies to increase water intake, decrease water loss, or store water when available. Some common adaptations include deep root systems, short life cycles, and minimizing water loss through small, leathery leaves or photosynthesis taking place in fleshy stems. Additionally, in irrigated drylands, farmers use extensive irrigation systems to grow crops in arid regions.
