DENDROLOGY

Detailed explanation-1: -Which of the following best explains how the structure of the leaf is used in processes that occur in plants? Carbon dioxide enters the plant through the surface of the leaf for cellular reproduction.

Detailed explanation-2: -Adaptations of leaves to maximise gas exchange: They are thin which gives a short diffusion distance. They are flat which provides a large surface area to volume ratio. They have many stomata which allow movement of gases in and out of the air spaces inside the leaf to maintain a steep concentration gradient.

Detailed explanation-3: -Stomata are responsible for allowing gas exchange between the inside of the leaf and the atmosphere. Stoma is the singular and stomata is the plural form.
