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: -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-3: -Plastids are the large cell organelles present only in plant cells. There are three types of plastids: chromoplast, leucoplast, and chloroplast. The plastid which contains a green pigment chlorophyll is called the chloroplast.

Detailed explanation-4: -In plants and algae, which developed much later, photosynthesis occurs in a specialized intracellular organelle-the chloroplast. Chloroplasts perform photosynthesis during the daylight hours.

Detailed explanation-5: -Chloroplasts are found in plant cells only because chloroplasts contain chlorophyll which is essential for photosynthesis. Chlorophyll traps sunlight and uses it to prepare food for plants by the process of photosynthesis.
