NEET BIOLOGY

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: -In plants, photosynthesis takes place in chloroplasts, which contain the chlorophyll. Chloroplasts are surrounded by a double membrane and contain a third inner membrane, called the thylakoid membrane, that forms long folds within the organelle.

Detailed explanation-3: -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-4: -In all autotrophic eukaryotes, photosynthesis takes place inside an organelle called a chloroplast. In plants, chloroplast-containing cells exist in the mesophyll.

Detailed explanation-5: -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.
