It is a process in living organisms involving the production of energy, typically with the intake of oxygen and the release of carbon dioxide from the oxidation of complex organic substances.
- Gaseous exchange: Intake of oxygen from the atmosphere and release of carbon dioxide.
- Breakdown of simple food in order to release energy inside the Cellular Respiration
Breakdown of Glucose by various pathways
Mechanism of Breathing
Exchange of Gases between alveolus blood and tissues
Terrestrial Organism: use atmospheric oxygen for respiration
Aquatic Organisms: use oxygen dissolved in water.
Respiration in Plants:
Respiration in plants is simpler than the respiration in animals. Gaseous exchange occure through
- Stomata in leaves
- Lenticels in stems
- The general surface of the roots.
