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

Detailed explanation-4: -Photosynthesis primarily takes place in the specilised structures called chloroplasts that have chlorophyll present in them. It is the chlorophyll that absorbs light energy from the sun. The leaves contain majority of the chloroplast which absorbs sunlight for the process of photosynthesis to take place.

Detailed explanation-5: -Interior to the chloroplast’s inner membrane and surrounding the thylakoids is a fluid called the stroma. The light-independent reactions of photosynthesis take place within the stroma. It contains enzymes that work with ATP and NADPH to “fix” carbon from carbon dioxide into molecules that can be used to build glucose.
