In what way are the light-dependent and light-independent reactions of photosynthesis similar?
both require chemical energy to proceed.
both occur in the chloroplast.
both produce oxygen as a byproduct.
both involve carbon fixation.

The correct answer is Both occurs in chloroplast.

Chloroplasts are organelle present in plant cell that  serves as the main site for photosynthesis. Both the light-dependent reaction and the light- independent reaction take place occurs in chloroplast. The light-independent reaction or the dark reactions occurs in the stroma, that is the fluid filled area of the chloroplast. The light dependent reaction takes place in the thylakoid membrane
