Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Where does the light independent reaction take place?
A
Matrix
B
Stroma
C
Thylakoid membrane
D
Cytoplasm
Explanation: 

Detailed explanation-1: -The light-independent reactions represent the known Calvin–Benson–Bassham (CBB) cycle which takes place in the stroma of chloroplasts and is the primary pathway of carbon fixation of C3 plants [119].

Detailed explanation-2: -(i) Light reactions occur in grana thylakoids whereas dark reactions occur in stroma of chloroplasts.

Detailed explanation-3: -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-4: -Once the light reactions have occurred, the light-independent or “dark” reactions take place in the chloroplast stroma.
