Explain Respiration in organisms.

All living cells must carry out cellular respiration, the process by which organisms break down glucose from the chemical bonds of food molecules and provide energy for the essential processes of life.

It can occur both aerobically (using oxygen), or anaerobically (without oxygen).

Respiration in plants takes place in the mitochondria of the cell in the presence of oxygen, which is known as "aerobic respiration".

The process of respiration in plants involves uses of sugars which are produced during photosynthesis, and oxygen to produce energy for plant growth.

Glucose               + Oxygen                                    Carbon-dioxide   +   Water

Respiration in animals takes place with the help of specialized systems that includes the Nose and nasal cavity, Pharynx, Larynx, Trachea, Bronchi, Lungs, & Alveoli.

The process of respiration in animals involves taking in oxygen and exchange it for carbon dioxide and water as waste products.
