Question

The structures that are foremed by stacking of organized flattened membranous sacs in the chloroplasts are:

• A. Stroma
• B. Cristae
• C. Grana
• D. Stroma lamellae

Answer 1

The correct option is C Grana

The structures that are foremed by stacking of organized flattened membranous sacs in the chloroplasts are called grana.
Chloroplasts are organelles in plant cells that conduct photosynthesis. It is made up of three layers:
- Smooth outer membrane
- Smooth inner membrane
- Thylakoid system
The thylakoid system is suspended in stroma, an aqueous fluid that is rich in protein and is present inside the inner membrane.
The thylakoid system is a collection of chlorophyll containing membranous sacks called thylakoids.
The thylakoids are arranged in stacks known as grana.
