Detailed explanation-1: -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. The chloroplast’s own genetic material (separate from that of the cell) is also stored in the stroma.

Detailed explanation-2: -The light independent process (also called dark reactions or the Calvin-Benson cycle) takes place in the stroma of the chloroplast. Carbon dioxide is modified by series of chemical reactions to form carbohydrates. The energy for these reactions comes from ATP and NADPH generated during the light dependent process.

Detailed explanation-3: -In the Calvin cycle, which takes place in the stroma, the chemical energy derived from the light-dependent reactions drives both the capture of carbon in carbon dioxide molecules and the subsequent assembly of sugar molecules. The two reactions use carrier molecules to transport the energy from one to the other.

Detailed explanation-4: -When carbon dioxide gets into the mesophyll cells, it circulates into the stroma of the chloroplast. Stroma is the spot where the light-independent reaction occurs. The light-independent reaction is also recognized as the Calvin-Benson cycle, Calvin Cycle, and dark reaction.

Detailed explanation-5: -1 Photosynthesis. In photosynthesis a blue/green substance called chlorophyll A and a yellow/green substance called chlorophyll B use light energy (normally sunlight but sometimes artificial) to change carbon dioxide and water into sugars (carbohydrates) and oxygen in the green parts of the plant.
