Differences between Respiration and Photosynthesis

Respiration and photosynthesis are biological reactions in the environment that complement each other. Both are similar reactions that occur in a reverse manner. In the process of respiration, oxygen and glucose yield water and carbon dioxide, while carbon dioxide and water yields glucose and oxygen in photosynthesis.

Both respiration and photosynthesis function adequately as living organisms provide carbon dioxide required for plants that undergo photosynthesis and produces glucose. Bacteria and plants release oxygen that is required for all living organisms for respiration.

Both cellular respiration and photosynthesis are the parts of a mutually beneficial relationship.  Photosynthesis cannot occur without cellular respiration and cellular respiration certainly cannot occur without the photosynthesis.

Definition of Photosynthesis

Photosynthesis is the process of preparation of food by the plants with the help of sunlight, water and carbon dioxide. The photosynthesis occurs in the chloroplasts of the plant and is considered as a photochemical reaction because it uses carbon dioxide, Water and light to form carbohydrates.

Definition of Respiration

It is the process of involves taking in oxygen into the cells, using it for releasing energy by burning food, and then eliminating the waste products are carbon dioxide and water from the body.

Differences between Respiration and Photosynthesis

Photosynthesis Respiration
Photosynthesis occurs only in Green plants and some photosynthetic bacteria. This process is common to all living things including plants, animals, birds, etc.
It synthesizes foods. It oxidizes foods.
It stores energy. It releases energy.
Photosynthesis is an anabolic process. It is a catabolic process.
It requires cytochrome. It also requires cytochrome.
It is Endothermal process. It is Exothermic process.
It comprises products like sugar, oxygen, and water as products. It comprises products like hydrogen and carbon-dioxide.
During Photosynthesis, radiant energy is converted into potential energy. During this process, potential energy is converted into kinetic energy.
Photosynthesis takes place during the day only because it is dependent on light. It is a continuous process and without this no organism can survive.
Photosynthesis consists of two stages light reaction and dark reaction. It consists of two stages, they are inhalation and exhalation.
