A thylakoid is a sheet-like membrane-bound structure that is the site of the light-dependent photosynthesis reactions in chloroplasts and cyanobacteria. It is the site that contains the chlorophyll used to absorb light and use it for biochemical reactions.
1:thylakoid membrane 2:Lumen 3:grana 4:stroma 1:thylakoid membrane-It is the site of light reaction of photosynthesis with photosynthetic pigment embedded into it, It is in the form of light & dark bands.These are mainly composed of phospholipids. 2-Lumen-It is the aqueous liquid enclosed by a thylakoid membrane.
