Question

define -: photosynthesis ..​

Answer 1

During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. ... This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules.

hope it helps!!!

Answer 2

The act of gathering light energy and converting it into chemical energy is known as photosynthesis. Light energy is used by green plants and other creatures to transform carbon dioxide and water into glucose. As a by-product of this process, oxygen is created.

Explanation:    

• Photons from sunlight are absorbed by plant leaves, which excite chlorophyll and activate electrons. The water received by plant roots is divided into oxygen and hydrogen ions in the first stage.
• The energised electrons then combine to generate ATP and NADPH. The electron chain is involved in this process. Similarly, oxygen is released into the atmosphere through leaves in similar process.
• The energy from the light reaction is then used to convert carbon dioxide into glucose in the next step. This entire process is divided into numerous sections. The reactions begin with 3-Ribulose biphosphate (RuBP) and conclude with the same molecule producing glucose. The Rubisco enzyme is a crucial component of the Calvin Cycle, as it is responsible for initiating all of the reactions
