Class 11 Biology Chapter 14 Respiration in Plants: Important Topics
The method by which cells get chemical energy by the consumption of oxygen and the liberating of carbon dioxide is called respiration. Plants do require oxygen to respire, the process in return gives out carbon dioxide. Unlike humans and animals, plants do not possess any specialized structures for the exchange of gases, however, they do possess stomata (found in leaves) and lenticels (found in stems) actively involved in the gaseous exchange. Leaves, stems, and plant roots respire at a low pace compared to humans and animals.

Cellular Respiration
Cellular respiration is a set of metabolic reactions taking place inside the cells to convert biochemical energy that is obtained from the food into a chemical compound called adenosine triphosphate (ATP).
-
Respiratory Quotient
The respiratory quotient(RQ) is referred to as the ratio of the volume of carbon dioxide evolved to the volume of oxygen consumed in the process of respiration. It can also be defined as the respiratory ratio, which is dependant on the type of respiratory substrate utilized during respiration.
