The figure given below shows the structure of a chloroplast with its four parts labelled as A, B, C and D. Select the part that is incorrectly matched with its function.

B: Granum—site of light-independent phase

A: Thylakoid—contains chlorophyll pigment in its membrane

C: Stroma—contains enzymes required for synthesis of carbohydrates and proteins

D: Inner membrane—Relatively less permeable than the outer membrane

Thylakoids removed from chloroplasts were kept in the illuminated culture having CO 2 and water, but sugar was not produced because of

Non-formation of assimilatory power.

Match column-I with column-II, and choose the correct option: Column I Column II a Thylakoids I The gel-like material of mitochondria b Cristae ii Infoldings in mitochondria c Cisternae iii Disc-shaped sacs in Golgi apparatus d Matrix iv Flat membranous sacs in the stroma
