Respiration is essential for growth and maintenance of all plant tissues, and plays an important role in the carbon balance of individual cells, whole-plants and ecosystems, as well as in the global carbon cycle.

Plant cells do not have mitochondria and therefore cannot respire using aerobic respiration. Anaerobic respiration occurs in the cytoplasm, therefore plants do experience anaerobic respiration.

Unlike aerobic respiration, anaerobic respiration does not need oxygen. It is the release of a relatively small amount of energy in cells by the breakdown of food substances in the absence of oxygen.

The respiration that occurs in the absence of oxygen is known as anaerobic respiration. In this process, the incomplete oxidation of food substance is being made by carbon dioxide CO2 and alcohol(OH). Beside this other organic matter such as citric acid, oxalic acid, lactic acid, etc are also produced.

There are two types of cellular respiration (see Cellular Respiration concept): aerobic and anaerobic. One occurs in the presence of oxygen (aerobic), and one occurs in the absence of oxygen (anaerobic).

Cellular respiration is a chemical process that takes place inside cells and produces energy. In our lungs, respiration can refer to the act of breathing.

The process of getting oxygen into the body and releasing carbon dioxide is called respiration. Breathing is only the movement of oxygen into the body and carbon dioxide out of the body. The process of respiration also includes the exchange of oxygen and carbon dioxide between the blood and the cells of the body.

Respiratory failure is a serious condition that develops when the lungs can’t get enough oxygen into the blood. Buildup of carbon dioxide can also damage the tissues and organs and further impair oxygenation of blood and, as a result, slow oxygen delivery to the tissues.

The functions of the respiratory system include gas exchange, acid-base balance, phonation, pulmonary defense and metabolism, and the handling of bioactive materials.

External respiration is the formal term for gas exchange. It describes both the bulk flow of air into and out of the lungs and the transfer of oxygen and carbon dioxide into the bloodstream through diffusion.

Brings air to body temperature and moisturizes it to the humidity level your body needs. Delivers oxygen to the cells in your body. Removes waste gases, including carbon dioxide, from the body when you exhale. Protects your airways from harmful substances and irritants.

Respiration is the process of releasing energy from food and this takes place inside the cells of the body. Respiration is essential for life because it provides energy for carrying out all the life processes which are necessary to keep the organisms alive.

There are 3 major parts of the respiratory system: the airway, the lungs, and the muscles of respiration. The airway, which includes the nose, mouth, pharynx, larynx, trachea, bronchi, and bronchioles, carries air between the lungs and the body’s exterior.
