NCERT Solutions for Class 11 Biology Chapter 14 – Respiration in Plants

Respiration is one of the fundamental processes that is carried out by living bodies. All the energy that is required for life processes is obtained by the oxidation of some macromolecules which comes from food. Autotrophs can synthesise their food through the photosynthesis process, wherein light energy is trapped and converted into chemical energy. Green plants, different tissues, and non-green cells require food for oxidation. So, food can be translocated to all the non-green parts. As we all know animals are heterotrophic, they derive their nutritional requirements from plants.

The chapter 14 deals with cellular respiration which is the mechanism of the disintegration of food materials inside the cell to release energy. This energy is trapped to synthesise ATP, which is the energy currency of any living cell.

Respiration in Plants

Plants like other animals also respire and also need energy. The plants get energy through the process of respiration in which glucose food breaks down to form carbon dioxide and water with the release of energy in presence of oxygen.

This energy is used by the plant for carrying out its many life processes. Like other organisms, plants also respire for their survival. The respiration in plants differs from animals. In plants, each part of plants  can independently take in oxygen from air, utilize it to obtain energy, and give out carbon dioxide.

Respiration In Leaves

The leaves of plants have tiny pores on their surface which are known as stomata. The exchange of gases during respiration takes place through stomata  in the leaves.

Oxygen from the air enters into a leaf through stomata and reaches all the cells by the process which is known as diffusion. This oxygen is used in respiration of the leaf. The carbon dioxide produced during diffuses out from the leaf into the air through the same stomata.

Respiration in Roots

As we know the roots of plants are under the ground but root cells also need oxygen to carry out respiration and release energy for their own use.

How Does Respiration Occur in Roots?

The roots of a plant take up air from the spaces between the soil particles and these root hairs are in contact with the air in the soil particles. O2 from the air in soil particles diffuse into root hair and reach all the cells of the root where it is utilised in respiration. Co2 produced in the cells of the root during respiration goes out through the same root hair by the process of diffusion.
