NEET BIOLOGY

Detailed explanation-1: -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-2: -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-3: -The site of photosynthesis in plants is the chloroplast. This cell organelle is found in plant cells and contains chlorophyll, a green-coloured pigment.

Detailed explanation-4: -Chloroplasts: These contain chlorophyll and are 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).
