The leaf is thin, and has a very large surface area - making it ideal for diffusion and absorbsion. The larger the surface area, the more sunlight can be absorbed. The leaf is also thin so that the mesophyll cells are closer to the surface - reducing the diffusion distance of CO2 from the surroundings to the mesophyll cells.

Leaves are flat so that maximum surface is available for capturing sunlight so that photosynthesis can take place. But some leaves are needle like to reduce evaporation by transpiration. Some are succulent to store water.

Leaves can be spines (cactus), tendrils (peas), needles (gymnosperms), strap-like (monocots) or blade-like (dicots). Each plant has formed its leaves to maximize survival.
