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

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.

Detailed explanation-4: -Photosynthesis happens when water is absorbed by the roots of green plants and is carried to the leaves by the xylem, and carbon dioxide is obtained from air that enters the leaves through the stomata and diffuses to the cells containing chlorophyll.
