Detailed explanation-1: -Stacks of thylakoids embedded with pigment molecules are called grana. The inner matrix of the chloroplast is called the stroma .

Detailed explanation-2: -Thylakoids are placed one above the other to form a stack-like structure called a granum. Thylakoid membrane contains the green pigment chlorophyll, which absorbs sunlight during the process of photosynthesis.

Detailed explanation-3: -Inside the chloroplasts are stacks of discs called thylakoids. They are compared to stacks of coins within the walls of the chloroplast, and they act to trap the energy from sunlight. The stacks of thylakoids are called grana. They are connected with an extensive sytem of tubules.

Detailed explanation-4: -Answer and Explanation: The stack of membranes that modifies, sorts and packages proteins, that arrive on the cis side of the structure from the endoplasmic reticulum is the Golgi apparatus.
