EVERYDAY SCIENCE

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: -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-3: -Answer and Explanation: The organelle that carries out photosynthesis is the chloroplast.

Detailed explanation-4: -Photosynthesis: Light Reactions Light reactions of photosynthesis occur in the thylakoid membranes of the grana in the chloroplast in the presence of sunlight.
