Final answer:
Maple leaves are living and important for the survival of the tree as they carry out processes like photosynthesis and respond to changes in the environment.
Step-by-step explanation:
Maple leaves are indeed alive. Leaves are one of the most important parts of a plant and are responsible for photosynthesis, which is how plants make their own food. The leaves contain cells that are alive and actively carry out processes like respiration, transpiration, and nutrient transport. They also respond to changes in the environment, such as closing their stomata to prevent water loss in dry conditions. So, maple leaves are living and vital for the survival of the tree.
