DENDROLOGY

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: -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-3: -Chloroplasts, the organelles responsible for photosynthesis, are in many respects similar to mitochondria. Both chloroplasts and mitochondria function to generate metabolic energy, evolved by endosymbiosis, contain their own genetic systems, and replicate by division.

Detailed explanation-4: -The chloroplast acts as the site of photosynthesis.

Detailed explanation-5: -In plants, chloroplasts are concentrated particularly in the parenchyma cells of the leaf mesophyll (the internal cell layers of a leaf).
