Detailed explanation-1: -Chlorophyll is located in a plant’s chloroplasts, which are tiny structures in a plant’s cells. This is where photosynthesis takes place.

Detailed explanation-2: -In plants, chloroplasts are concentrated particularly in the parenchyma cells of the leaf mesophyll (the internal cell layers of a leaf).

Detailed explanation-3: -There are two distinct regions present inside the chloroplasts. One is grana and the other is stroma. Grana is made up of stacks of disc-shaped structures known as thylakoids. These contain the chlorophyll molecule.

Detailed explanation-4: -In plants and algae, which developed much later, photosynthesis occurs in a specialized intracellular organelle-the chloroplast. Chloroplasts perform photosynthesis during the daylight hours.

Detailed explanation-5: -Plant cells have certain distinguishing features, including chloroplasts, cell walls, and intracellular vacuoles. Photosynthesis takes place in chloroplasts; cell walls allow plants to have strong, upright structures; and vacuoles help regulate how cells handle water and storage of other molecules.
