Detailed explanation-1: -Photosynthesis is a two-step process. In chloroplasts, chlorophyll molecules absorb sunlight and pass the extra energy to molecular partners that use it to generate the energy-storing chemicals adenosine triphosphate (ATP) and nicotinamide adenine dinucleotide phosphate (NADPH).

Detailed explanation-2: -Abstract. Chloroplasts migrate in response to different light intensities. Under weak light, chloroplasts gather at an illuminated area to maximize light absorption and photosynthesis rates (the accumulation response). In contrast, chloroplasts escape from strong light to avoid photodamage (the avoidance response).

Detailed explanation-3: -Chloroplasts are filled with the pigment chlorophyll, which is vital in photosynthesis. The chlorophyll is able to harness solar energy to help create chemical energy from solar energy.

Detailed explanation-4: -Movement of Chloroplasts They jostle and slide and scoot around the cell, often sticking near the edges of the cell but sometimes seeming to fill the cell entirely with constant motion. The motion is common to the interior of cells and is called cyclonic or cytoplasmic streaming.
