What essential role do leaves play in plants?

• A. Absorb nutrients from soil
• B. Provide structural support
• C. Engage in photosynthesis to produce food
• D. Facilitate water transport

Answer: (C)

Leaves play a crucial role in the process of photosynthesis, which is how plants produce their own food. During photosynthesis, leaves capture sunlight and use it to convert carbon dioxide from the air and water from the soil into glucose, a type of sugar that serves as energy and building material for the plant. This process is essential not only for the plant itself but also for the ecosystem, as it produces oxygen as a byproduct, which is vital for most living organisms. The structure of leaves, with their broad surface area and chlorophyll pigments, maximizes their ability to absorb light and facilitate gas exchange through tiny openings called stomata. This demonstrates the significant role that leaves play beyond just being a part of the plant; they are integral to maintaining life on Earth through the production of food and oxygen.
