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.
