Explanation:
Detailed explanation-1: -The large surface area of the plant helps it to absorb as much sunlight as possible which is required for making food for the plant through the process of photosynthesis.
Detailed explanation-2: -Leaves are broad with a large surface area so that they are exposed to more light and can maximize light absorption.-They are thin and flat so that carbon dioxide has a shorter distance to diffuse and the diffusion therefore occurs at a faster rate.
Detailed explanation-3: -Photosynthesis is the process by which leaves absorb light and carbon dioxide to produce glucose (food) for plants to grow. Leaves are adapted to perform their function, eg they have a large surface area to absorb sunlight.
