Detailed explanation-1: -In plants and algae, which developed much later, photosynthesis occurs in a specialized intracellular organelle-the chloroplast. Chloroplasts perform photosynthesis during the daylight hours. The immediate products of photosynthesis, NADPH and ATP, are used by the photosynthetic cells to produce many organic molecules.

Detailed explanation-2: -In plants, photosynthesis takes place in chloroplasts, which contain the chlorophyll. Chloroplasts are surrounded by a double membrane and contain a third inner membrane, called the thylakoid membrane, that forms long folds within the organelle.

Detailed explanation-3: -Photosynthesis takes place in the plastids of a cell, also called a chloroplast. The chloroplast contains a green pigment called chlorophyll which is very essential for photosynthesis. The cell organelle in which photosynthesis takes place is plastids.

Detailed explanation-4: -On the cellular level, the reactions for photosynthesis occur in organelles called chloroplasts (in eukaryotic cells).
