41] Leaves are broad and thin to minimize their absorption of oxygen

False

leaves are the main site for the process of photosynthesis most leaves are broad and so have a large surface area allowing them to absorb more light.

is thin for the diffusion of carbon dioxide in and oxygen out easily.

broad and thin leaves provides a large surface for light absorption and short distances for gaseous diffusion.
