These processes are related to each other. Actually, it is the same process but in reverse. Photosynthesis is a process that takes carbon dioxide from the atmosphere and turns it into oxygen. On the other hand, respiration does the opposite, taking oxygen from the environment and turning it into carbon dioxide. The basic difference between photosynthesis and respiration is that photosynthesis occurs only in plants and some photosynthetic bacteria. On the other hand, respiration occurs in all living organisms.
Photosynthesis Vs. Respiration – Overview
Photosynthesis and respiration are two processes that plants carry out, generally at the cellular level. They play vital functions for plants and are performed at the same time, without interruptions. Photosynthesis is the process in which plant takes out a set of metabolic and cellular actions to make their own food, with the use of a set of raw materials that they take from the environment, such as water, oxygen, and light energy from the Sun. while in respiration, it is carried out at the same time at the cellular level using oxygen, releasing energy after capturing compounds such as CO 2 and water. Glucose is split to produce energy during respiration.
Difference Between Photosynthesis And Respiration In Tabular Form
|Photosynthesis is done only on green plants.||It occurs both in plants and animals.|
|During the photosynthesis process, compounds that have a lot of energy are formed.||During respiration, glucose is split to release energy.|
|In photosynthesis, the light uses H2O and CO2 to synthesize glucose.||During respiration, H2O and CO2 are eliminated.|
|It releases oxygen.||It Consumes or uses oxygen.|
|Energy accumulates.||Releases energy.|
|Simple chemical compounds are used to obtain complex compounds, carbohydrates, and others.||Complex compounds are used to produce simple compounds = H2O and CO2.|
|It is an endothermic reaction and it requires energy.||Respiration is an exergonic reaction as energy is released.|
|Anabolic process.||Catabolic process.|
What is Photosynthesis?
Photosynthesis is a process that ends with the release of oxygen as a product, and the production of glucose in the form of cellulose, which is the food of plants. During photosynthesis, plants capture water, carbon dioxide, and nutrients from the air, and with the help of solar energy. And they make their own food, releasing glucose for themselves as a final product, and oxygen to the environment that will be used by other beings. alive and by itself as raw material to breathe. This process takes place or is carried out and thanks to the pigment called chlorophyll, which is stimulated by sunlight. The released oxygen by plants is also used by them and other living beings.

What is Respiration?
Respiration in plants occurs differently that uses oxygen from the air, and at the cellular level, glucose is converted into pyruvic acid by the mitochondria, and then pyruvic acid is converted into carbon dioxide (CO 2 ) and water (H 2 O ). Meanwhile, there is an important production of ATP molecules with the release and capture of energy. During respiration in plants, unlike that of other living beings, is carried out at the cellular level.
- Photosynthesis is a process that takes place in the chloroplast, also cellular. While respiration is a cellular process that takes place in the mitochondria.
- Photosynthesis is an exclusive process of plants.
- Whereas, respiration is a process that other living beings also carry out.
- Photosynthesis transforms light energy from the Sun into chemical energy.
- Respiration can transform chemical energy into energy that will be used in the synthesis of the glucose molecule and other plant processes
- Photosynthesis is an anabolic process. whereas, respiration is a catabolic process.
- Photosynthesis releases oxygen into the environment and glucose is produced; While, respiration consumes glucose and chemical energy, with which it produces energy and uses it.
