c) Respiration takes place both during day and night.
Respiration is a chain of chemical reactions that enables all living entities to synthesize energy required to sustain.
Respiration in Plants
During respiration, in different plant parts, significantly less exchange of gas takes place. Hence, each part nourishes and fulfils its own energy requirements.Consequently, leaves, stems and roots of plants separately exchange gases. Leaves possess stomata – tiny pores, for gaseous exchange. The oxygen consumed via stomata is used up by cells in the leaves to disintegrate glucose into water and carbon dioxide
