Q: Answer the following question given this paragraph: After leaves turn color in the fall, they may all fall off the plant for the winter. Plants that shed their leaves seasonally each year are called deciduous plants . Shedding leaves is a strategy for reducing water loss during seasons of extreme dryness. On the downside, the plant must grow new leaves in the spring, and that takes a lot of energy and matter. Some plants may "bank" energy over the winter by storing food. That way, they are ready to grow new leaves as soon as spring arrives. Q: What do we call plants that shed their leaves seasonally each year? Choices: - perennials - annuals - lush plants - deciduous plants A:
A: deciduous plants
