Photosynthesis in plants occurs in two stages. These stages are known as the light-dependent reactions and the Calvin Cycle.
The first stage of photosynthesis is the light dependent reactions. These reactions take place on the thylakoid membrane inside the chloroplast. During this stage light energy is converted to ATP (chemical energy) and NADPH (reducing power).
<span>The second stage of photosynthesis is the Calvin Cycle. These reactions occur in the stroma of the chloroplast. Energy from ATP and electrons from NADPH are used to convert carbon dioxide into glucose and other products.</span>
The sun rays are received by the plants and explell oxygen and we breath the oxygen to be able to survive
