Detailed explanation-1: -In plants, the so-called “light” reactions occur within the chloroplast thylakoids, where the aforementioned chlorophyll pigments reside. When light energy reaches the pigment molecules, it energizes the electrons within them, and these electrons are shunted to an electron transport chain in the thylakoid membrane.

Detailed explanation-2: -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-3: -The thylakoid membrane is the site of photochemical and electron transport reactions of oxygenic photosynthesis. The lipid composition of the thylakoid membrane, with two galactolipids, one sulfolipid, and one phospholipid, is highly conserved among oxygenic photosynthetic organisms.

Detailed explanation-4: -They do this through a process called photosynthesis, which uses a green pigment called chlorophyll. A pigment is a molecule that has a particular color and can absorb light at different wavelengths, depending on the color.

Detailed explanation-5: -The photosynthetic membranes, thylakoids contain photosynthetic pigments like chlorophyll a and chlorophyll b. Thylakoids are membrane-bound and have several compartment-like structures inside them. The membranes of thylakoid contain chlorophyll pigments and are found in packets called quantasomes.
