GENERAL HISTOLOGY

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 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-3: -In a plant cell, chloroplast makes sugar during the process of photosynthesis converting light energy into chemical energy stored in glucose.

Detailed explanation-4: -In plants, chloroplasts occur in all green tissues, though they are concentrated particularly in the parenchyma cells of the leaf mesophyll.

Detailed explanation-5: -It’s within the chloroplast that photosynthesis takes place in plants, turning sunlight and carbon dioxide into sugar and oxygen. The chloroplast and the chlorophyll within it are the reason plants can make their own energy without having to consume other organisms.
