Final answer:
Creeping bentgrass is more drought-resistant than perennial ryegrass due to its deeper and more extensive root systems and efficient water-use strategies.
Step-by-step explanation:
Creeping bentgrass is indeed more drought-resistant than perennial ryegrass. Drought resistance refers to the ability of a plant to withstand or tolerate dry conditions. Creeping bentgrass has deeper and more extensive root systems, allowing it to access water from deeper in the soil. It also has more efficient water-use strategies, such as minimizing water loss through its leaves. On the other hand, perennial ryegrass is less adapted to dry conditions and requires more water to survive.
