Solution

The correct option is C

grana


The light reaction takes place in grana of the chloroplasts. Grana are stacks of membrane-bound sacs called as thylakoids which are present within the chloroplasts. During this phase, energy from the sunlight is absorbed by the pigment chlorophyll and is converted into chemical energy.

Dark reaction occurs in the stroma of the chloroplasts. Dark reaction phase is also called 'Calvin cycle'.
