 In leaves, the exchange of respiratory gasses takes place through very small pores called stomata (singular stoma). The stomata are present in large number on the lower surface of leaves of a plant. Each stoma has a pore at its center which is surrounded and controlled by two kidney-shaped cells called guard cells. When the stoma opens the exchange of gasses takes place between the atmosphere and interior of the leaf by the process of diffusion.

The body can rapidly metabolize carbohydrates, making this macronutrient the favored energy source for your body. In contrast, the vital macronutrient protein breaks down your body's cells and rebuilds them.
