Light reaction of photosynthesis occurs in granum part of chloroplast.

Explanation:

Photosynthesis occurs in chloroplast that contains chlorophyll pigment. Light is entrapped by chlorophyll pigment that is present in granum part of chloroplast. Thus light reaction occurs in granum part of chloroplast.

Dark reaction occurs in stroma part of chloroplast as it does not require light directly but is dependent upon the end products of light reaction.
