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 eukaryotic cells like plant cells, photosynthesis takes place in an organelle called a chloroplast that contains a light-absorbing pigment called chlorophyll.

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: -All green plants and algae of eukaryotes contain chloroplasts. These are organelles that contain the photosynthetic pigment, and chlorophyll, and thus are crucial for the green plants.
