Revision Notes For For Class 11 Biology Chapter 14 Respiration In Plants

Respiration is a metabolic process which is carried out by all living organism including plants, animals, and humans for the production of energy and to stay alive. Respiration in plants is the process used by plants for converting nutrients into energy which are required for the cellular activities.

Alike animals and humans, plants do not have any specialized organ for the respiration process. During this process, different parts of the plants are involved in the exchange of gases. Roots, stems, and leaves are involved in the respiration process and it takes place in the mitochondria of the cell in the presence of oxygen. There are two types of respiration in plants

Dark respiration: This metabolic process occurs in the presence or absence of light

Photo or light respiration: This metabolic process mainly occurs exclusively in the presence of light.

Frequently asked Questions on CBSE Class 11 Biology Notes Chapter 14: Respiration in Plants


What is ‘Aerobic respiration’?

A chemical process in which oxygen is used to make energy from carbohydrates (sugars).


What is ‘Photosynthesis’?

Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.


Where is ATP synthesised in plants?

n plants, ATP is synthesized in the thylakoid membrane of the chloroplast. The process is called photophosphorylation.
