Question

The grana and stroma lamellae are the parts of

• A. Mitochondria.
• B. Chloroplast.
• C. Ribosomes.
• D. Golgi bodies.

Answer 1

The correct option is B Chloroplast.

The chloroplast is the double-membraned structure which is involved in the process of photosynthesis and is composed of grana and stroma. Each granum is made up of a stock of closed compartment called thylakoids which contain pigments for absorbing light. The stroma is the fluid part in the chloroplast. Grana are the sites for the light reaction and stroma is the site for the dark reaction of photosynthesis.

Thus, the correct answer is option B.
