membranous sections of the chloroplast

rina.r · Answer

The light-dependent reactions take place in the membranous sections of the chloroplast - thylakoids (granae/lamellae) - which offer a large surface area to absorb light energy.
The main function of these reactions is to provide a source of ATP and reduced NADP which are used to reduce CO2 in the light independent reactions. 

Light dependent reactions occur in the thylakoid membrane of the chloroplasts in photosynthetic organisms. The products (ATP and NADPH) are used in the second stage of photosynthesis, which is called the Calvin Cycle.
