Name the organ and site of photosynthesis in green plants. List the raw materials essential for this process
to take place. How are they obtained by the green plants? Write balanced chemical equation for the process, stating the by product of the reaction.

Dear student,
Essentially, the chloroplast is an independent fully functional organelle. Although all the green parts of a plant can carry out photosynthesis, it mainly occurs in the leaves due to the high abundance of chloroplasts. A chloroplast contains stroma, fluid, and stack of thylakoids called grana.

Photosynthesis is the process by which plants, some bacteria and some protistans use the energy from sunlight to produce glucose from carbon dioxide and water. This glucose can be converted into pyruvate which releases adenosine triphosphate (ATP) by cellular respiration. Oxygen is also formed.

Photosynthesis may be summarised by the word equation:

carbon dioxide + water arrow with sunlight and chlorophyll glucose + oxygen

The conversion of usable sunlight energy into chemical energy is associated with the action of the green pigment chlorophyll.

Regards
