The given diagram illustrates the process of photosynthesis.
Overall, it can be seen that this process consists of several stages, beginning from absorption of sunlight to producing oxygen.
To embark, the first stage of this process is the absorption of light energy from the sun, which makes the plants look green. In the subsequent stage, it consumes carbon dioxide through the stomata. Furthermore, water is absorbed through the roots and carried through the stem to the rest of the plants, and when sunlight, carbon dioxide, and water combine in the leaf, it makes sugar, and the excessive amount of sugar is stored as starch (food) in the roots.
In the next stage, oxygen and water particles vaporize from the leaf through the stomata, and that water loss from leaves is called transpiration. Following the previous stage, water loss is replaced by the plant’s roots during transpiration. Finally, the process ends at releasing oxygen particles in the air, and this entire process is called photosynthesis.
