Question

There is a clear division of labor in chloroplast . substantiate

Answer 1

Membranous system is present within the chloroplast consisting of grana, the stroma lamellae, and the fluid stroma which is responsible for division of labour. These membrane systems bring partitions within the chloroplast where different activities can be carried out. In stroma, dark reactions of photosynthesis occur. In membrane of thylakoids (parts of granum), light reactions are carried out .

Answer 2

There is clear division of labour within the chloroplast. the membrane system is responsible for the light reaction ( trapping light energy and synthesis of ATP and NADPH) while dark reaction i.e., enzymatic reactions for the reduction of carbon dioxide into sugar using ATP and NADPH take place in the stroma
