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 can only occur in specific cells of the plant that contain chlorophyll such as cells of leaves. Thus, all the cells of a plant can not perform photosynthesis.

Detailed explanation-3: -However, not all parts of a plant structure are suitable to do this, so not all types of plant cells contain chloroplasts. The plant cells that make up the roots and/or tubers typically do not contain chloroplasts since it would be useless to have them.

Detailed explanation-4: -Chlorophyll is located in a plant’s chloroplasts, which are tiny structures in a plant’s cells. This is where photosynthesis takes place.

Detailed explanation-5: -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.
