The correct Answer is:
### Step-by-Step Solution: 1. **Definition of Xerophytic Leaves**: - Xerophytic leaves belong to plants that are adapted to dry environments, such as deserts. These plants have developed specific features to minimize water loss. 2. **Thick Cuticle**: - One of the primary features of xerophytic leaves is the presence of a thick cuticle. The cuticle is a waxy layer that covers the leaf surface, which helps to reduce water loss through evaporation. A thicker cuticle means less transpiration, allowing the plant to conserve water. 3. **Sunken Stomata**: - Xerophytic leaves often have stomata that are sunken into the leaf surface. This adaptation reduces the exposure of the stomata to wind and direct sunlight, which decreases the rate of transpiration. By having stomata on the lower epidermis, the plant minimizes water loss. 4. **Reduced Surface Area**: - Xerophytic leaves typically have a smaller surface area compared to leaves of plants in wetter environments. A smaller surface area helps to reduce the amount of water lost through evaporation. 5. **Leathery Texture**: - The leaves of xerophytic plants may also have a leathery texture, which contributes to their ability to retain water. This texture, combined with the thick cuticle, helps to further reduce water loss. ### Summary of Features: - Thick cuticle to minimize evaporation. - Sunken stomata located on the lower epidermis to reduce transpiration. - Reduced surface area to limit water loss. - Leathery texture to aid in water retention.
