Definition - What does Photosynthesis mean?

Photosynthesis is the process used by plants and other organisms to convert sunlight into chemical energy to fuel their many activities. The chemical energy obtained through the photosynthesis process is synthesized from water and carbon dioxide and is stored in the organism’s carbohydrate molecules.

The process of photosynthesis is crucial to the production of oxygen and to sustaining life on earth as it supplies life forms with their required energy and organic compounds.

MaximumYield explains Photosynthesis

The process of photosynthesis is essentially what brings nourishment to plants. It starts out with the plant absorbing sunlight, water, and carbon dioxide. The plant takes in carbon dioxide from the air, bringing it to its leaves, while the plant's roots latch on to water and guide it to various vessels.

The process of photosynthesis occurs mainly in the leaves of the plant, which contain tiny cells that absorb as much sunlight as possible through the use of chlorophyll.

In the photosynthesis process, the sun’s energy is then used to divide the water absorbed by the roots into different molecules like oxygen and hydrogen. As the plants "breath", the oxygen is diffused back into the earth’s atmosphere, while the plant conserves the carbon dioxide and hydrogen, which it will later convert into energy and glucose. The glucose ends up contributing to the plant’s healthy development and growth, and some of it is stored in the fruits, roots, and leaves for later use.
