Respiration in plants :

• Like animals, plants also need energy. The plants get this energy by the process of respiration. Plants also use oxygen of air for respiration and release carbon dioxide.
• The respiration in plants differs from the animals in three respects:
• Plants have a branching shape, so they have quite a large surface area in comparison to their volume. Therefore, diffusion alone can supply all the cells of the plants with as much oxygen as they need for respiration.
• Diffusion occurs in the roots, stems and leaves of plants.
• Net gaseous exchange in the leaves of the plant: net gas exchange in leaves at night is: O2 diffuses in; CO2 diffuses out.

Respiration in animals :

In this process, animals intake oxygen and release carbon dioxide. It is also known as breathing. This is mainly two phases.

• Inspiration: It is the process by means of which oxygen is taken to the lungs.
• Expiration: During expiration, carbon dioxide is expelled out from the respiratory organs into the environment.
