Detailed explanation-1: -The grana of the chloroplast consists of chlorophyll pigments and are the functional units of chloroplasts. Stroma is the homogenous matrix which contains grana and is similar to the cytoplasm in cells in which all the organelles are embedded. Stroma also contains various enzymes, DNA, ribosomes, and other substances.

Detailed explanation-2: -Granum is a basic structural unit of the thylakoid membrane network of plant chloroplasts. It is composed of multiple flattened membranes forming a stacked arrangement of a cylindrical shape.

Detailed explanation-3: -The chloroplast is a plastid that is made up of an outer membrane, an inner membrane, grana, and the stroma. It’s within the chloroplast that photosynthesis takes place in plants, turning sunlight and carbon dioxide into sugar and oxygen.

Detailed explanation-4: -Granum act to increase the surface area of the thylakoids, which results in more light being absorbed into the chlorophyll. When you increase the surface area, you allow more materials to attach to the surface, or in this case, react in the different photosystems in the thylakoid membrane.

Detailed explanation-5: –Granum Is considered as basic functional units of chloroplasts. Granum are stacks of membrane-bounded, flattened discoid sacs called thylakoids containing the molecules of chlorophyll.-Light reactions of photosynthesis are performed in granum while dark reactions are performed in the stroma.
