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: -On the cellular level, the reactions for photosynthesis occur in organelles called chloroplasts (in eukaryotic cells).

Detailed explanation-3: -Photosynthesis is a process of manufacturing food in the presence of sunlight, with the help of water and carbon dioxide. Photosynthesis is seen in organisms of the kingdom Plantae. Cyanobacteria and other algae also exhibit photosynthesis. Photosynthesis is referred to as the autotrophic mode of nutrition.

Detailed explanation-4: -Chloroplasts are disc-shaped organelles found in the cytosol of a cell. They have outer and inner membranes with an intermembrane space between them.

Detailed explanation-5: -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.
