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: -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-3: -The most important function of the chloroplast is to synthesise food by the process of photosynthesis. Absorbs light energy and converts it into chemical energy. Chloroplast has a structure called chlorophyll which functions by trapping the solar energy and is used for the synthesis of food in all green plants.

Detailed explanation-4: -Chloroplasts are specialized for photosynthesis and are unique in that they contain the internal thylakoid membrane system.

Detailed explanation-5: -In particular, organelles called chloroplasts allow plants to capture the energy of the Sun in energy-rich molecules; cell walls allow plants to have rigid structures as varied as wood trunks and supple leaves; and vacuoles allow plant cells to change size.
