What is the process of photosynthesis?

Question

It is the process in which plants produce glucose.

Photosynthesis is the process in which plants make glucose from the suns light energy, water and carbon dioxide.

The light energy comes from the sun, which is constantly undergoing nuclear fusion (using hydrogen) and is absorbed by the palisade cells, which are optimised for energy absorbton. Water and carbon dioxide enter the leaf through the stomata (small holes on the underside f the leaf that are controlled by gaurd cells) by diffusion. The produced oxygen leaves the leaf in the same way, and the glucose is stored, used in respiration or used to make other vital substances.

Here is video of the light reaction of photosynthesis taking place in an aquatic plant - you can see the bubbles of oxygen leaving the vascular tissue of the plant where it was cut.

This reaction occurs in the chloroplasts of the plant cells (they contain chlorophyll, a green pigment, which is what gives plants their green colour).

undefined The process of turning light energy from the sun into chemical energy stored in glucose molecules is known as photosynthesis. It takes place in chloroplasts, mainly in plant leaves, and is based on the following equation: 6 CO2 + 6 H2O + light energy → C6H12O6 + 6 O2. Put another way, light energy is combined with carbon dioxide and water to produce glucose and oxygen. This process is divided into two main stages: the light-dependent reactions and the light-independent reactions (Calvin cycle). During the light-dependent reactions, light energy is absorbed by chlorophyll and converted into chemical energy in the form of ATP and NADPH. In the Calvin cycle, the ATP and NADPH that are produced in the light-dependent reactions are used to convert
