explain ....respiration in plants
Answers
The process of respiration in plants involves using the sugars produced during photosynthesis plus oxygen to produce energy for plant growth. ... Respiration takes place in the mitochondria of the cell in the presence of oxygen, which is called "aerobic respiration".
Answer:
Respiration is a chain of chemical reactions that enables all living entities to synthesize energy required to sustain.
It is a biochemical process wherein air moves between the external environment and the tissues and cells of the species. In respiration, inhalation of oxygen and exhalation of carbon dioxide gas takes place. As an entity acquires energy through oxidising nutrients and hence liberating wastes, it is referred to as a metabolic process.
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.
Roots, the underground part of the plants, absorbs air from the air gaps/spaces found between the soil particles. Hence, absorbed oxygen through roots is utilized to liberate the energy that in the future, is used to transport salts and minerals from the soil.
