SSC MTS EXAM

Detailed explanation-1: -The thylakoid membranes of a chloroplast is an internal system of interconnected membranes, that carry out the light reactions of photosynthesis. They are arranged into stacked and unstacked regions called grana and stroma thylakoids, respectively, that are differentially enriched in photosystem I and II complexes.

Detailed explanation-2: -Each thylakoid membrane contains many chlorophyll molecules and other proteins. Chlorophyll molecules are arranged into clusters called photosystems. Plants capture light energy with chlorophyll pigments and transfer it to electrons, which are then passed down the chain of proteins in the thylakoid membrane.
