Question

Choose the statements that are true regarding chloroplast:
i. The only double membrane bound organelle present in the plant cells
ii. Contains stroma, grana and stromal lamella
iii. Sugar is synthesized in the stroma
iv. Membrane system traps the light energy

• A. Only i and ii is correct
• B. Only iii and iv are correct
• C. All are correct
• D. All are correct except i

Answer 1

The correct option is D All are correct except i

Chloroplast is not the only double membrane-bound organelle present in the plant cells. Mitochondria, nucleus, chloroplasts are examples of double membrane-bound organelles present in the plant cells.
Grana, stroma, stromal lamella and inner membranes are some of the other components of the chloroplast. Light dependent reactions of photosynthesis take place in grana. Stromal lamella is used to connect the grana thylakoids. One of the major functions of stromal lamella is that it acts as the skeleton of the chloroplast and ensures that chloroplast has maximum efficiency. The membrane system plays a prominent role in trapping the sunlight necessary for photosynthesis.
