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 eukaryotes, photosynthesis takes place inside an organelle called a chloroplast. Some prokaryotes can perform photosynthesis, but they do not contain chloroplasts (or other membrane-bound organelles).

Detailed explanation-3: -On the cellular level, the reactions for photosynthesis occur in organelles called chloroplasts (in eukaryotic cells).

Detailed explanation-4: -In addition to the nucleus, eukaryotic cells may contain several other types of organelles, which may include mitochondria, chloroplasts, the endoplasmic reticulum, the Golgi apparatus, and lysosomes.

Detailed explanation-5: -The chloroplast contains a green pigment called chlorophyll which is very essential for photosynthesis. The cell organelle in which photosynthesis takes place is plastids. Plastids are double membrane-bound organelle that has their DNA and acts as a semi-autonomous organelle.
