Detailed explanation-1: -Stacks of thylakoids embedded with pigment molecules are called grana.

Detailed explanation-2: -Granum: It is the single disc-like disc-like structure present in the chloroplast. Grana. Granum. It is the stack or collection of disc-like structures present in the chloroplast. It the single disc-like structure present in the chloroplast, which is known as Thylakoid.

Detailed explanation-4: -Grana is the plural form of granum, which is the single form. The stroma lamellae connect two grana. Chloroplasts are made up of grana and stroma lamellae. The photosynthetic light reaction takes place in grana.

Detailed explanation-5: -Grana, the plural of granum, are piles of designs called thylakoids, which are little plates of layer on which light-subordinate photosynthesis responses happen. Stroma is comprised of photosynthetic proteins, starch grains, DNA, and ribosomes.
