The diagram of the ultrastructure of a plant cell is given below. Identify the function of the organelles labelled A, B, C, D, E, in the diagram.

A) A-Site of photophosphorylation, B-Storage of cell sap, C-Intracellular transport, D-Site of oxidative phosphorylation, E-Principal director of macromolecular traffic

B) A-Storage of cell sap, B-Site of oxidative phosphorylation, C-Principal director of macromolecular traffic, D-Site of photophosphorylation,   E-Intracellular transport

C) A-Intracellular transport, B-Site of oxidative phosphorylation, C-Principal director  of  macromolecular  traffic, D-Site    of    photophosphorylation, E-Storage of cell sap

D) A-Principal director of macromolecular traffic, B-Site of oxidative phosphorylation C-Intracellular   transport,   D-Site   of photophosphorylation, E-Storage of cell sap

Correct Answer: D

Solution :

A-Principal director of macromolecular traffic (Golgi bodies) B-Site of oxidative phosphorylation (Mitochondria) C-Intracellular transport (ER) D-Site of phosphorylation (Chloroplast) E-Storage of cell sap (Vacuole).
