1. Leaves have a large surface area so more light hits them.
2. A leaf is optimized to absorb light and carry out photosynthesis
Explanation:
A leaf usually has a large surface area, so that it can absorb a lot of light. Its top surface is protected from water loss, disease, and weather damage by a waxy layer. The upper part of the leaf is where the light falls, and it contains a type of cell called a palisade cell. This is adapted to absorb a lot of light.
