DENDROLOGY

Detailed explanation-1: -The dark reaction occurs in the stroma of the chloroplast, where they utilize the products of the light reaction. Plants capture the carbon dioxide from the atmosphere through stomata and proceed to the Calvin cycle.

Detailed explanation-2: -When the reaction of photosynthesis does not require light energy is called as a light-independent or dark reaction. It is also called as a biosynthetic phase or Calvin cycle. It occurs in the stroma of the chloroplast.

Detailed explanation-3: -The dark reactions of photosynthesis occur in the stroma (aqueous fluid surrounding the stacks of thylakoids) of the chloroplast where they utilize the products of the light reaction. In the dark reaction, plants use carbon dioxide with ATP and NADPH from the light reactions to produce glucose.

Detailed explanation-4: -ATP produced during light reaction is used up in the dark reaction of photosynthesis. The dark phase does not require the activation of sunlight and it occurs in the stroma of the chloroplast.
