Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is the Grana?
A
Stacks of thylakoids.
B
Stacks of lamella
C
Colorless fluid
Explanation: 

Detailed explanation-1: -Chloroplasts contain a system of membrane sacs, the thylakoids, some of which are stacked to form grana (singular, granum), whereas others float freely in the stroma . It is on the thylakoid membranes that the electron carriers necessary for photosynthesis reside.

Detailed explanation-2: -Each granum is made up of a stack of closed compartment called thylakoids. Each thylakoid consists of two parallel membranes joined at their margins. The membranes of thylakoids contain the layer of particles called chlorophyll.

Detailed explanation-3: -Final answer: The stack of thylakoids of chloroplast is called a granum.

Detailed explanation-4: -A stack of thylakoids is known as “Granum". It increases the surface area of the chloroplasts.
