Question

Pick out the various constituent(s) found within a chloroplast.

(i) Stroma
(ii) Ribosomes
(iii) Grana thylakoids
(iv) Stromal lamellae

• A. (i) and (iii) only
• B. (iii) and (iv) only
• C. (i), (iii) and (iv) only
• D. All of the above

Answer 1

The correct option is D All of the above

Structure of chloroplast:-

All of these structures are present within the chloroplast and perform unique functions. Synthesis of sugar takes place within the stroma. Ribosomes help in the synthesis of proteins. Light dependent reactions of photosynthesis take place in grana. The grana thylakoids are connected using specialised structures called stroma lamellae. Stroma lamella acts as the skeleton of the chloroplast and ensures that chloroplast has maximum efficiency.
