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: -The chloroplast contains a green pigment called chlorophyll which is very essential for photosynthesis. The cell organelle in which photosynthesis takes place is plastids. Plastids are double membrane-bound organelle that has their DNA and acts as a semi-autonomous organelle.

Detailed explanation-3: -Chloroplasts produce energy through photosynthesis and oxygen-release processes, which sustain plant growth and crop yield. As such, chloroplasts are responsible for the biosynthesis of active compounds such as amino acids, phytohormones, nucleotides, vitamins, lipids, and secondary metabolites [9].

Detailed explanation-4: -Answer: Solution 9: 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.

Detailed explanation-5: -Photosynthesis takes place in the chloroplasts of the plant cell. Chloroplasts are tiny membrane-bound organelles found within the cytoplasm of the plant cell. Chloroplasts are the main site of photosynthesis.
