Photosynthesis is the process by which green plants make their own food using energy from sunlight, water and carbon dioxide.
Photosynthesis takes place in organelles called chloroplast found mainly in the palisade mesophyll in the leaves of a green plants. The process occurs in two stages; light-dependent stage and light-independent stage.
The light dependent stage occurs in the thylakoid membranes of the chloroplast, while the light-independent stage occurs in the stroma of the chloroplast.
The overall charge of an atom is neutral because it has the same amount of protons and neutrons. They are positive and negative so they cancel each other out.
