[1 mark](b) (i) In Diagram 1, label the vascular bundle with the letter V. [1 mark] (ii) Name two types of tissues in V, which involve in transportation. [2 marks] (iii) State the function of any one of the tissues you have named in (b)(ii). [1 mark](c) (i) Explain the structural specialisation of cell P and Q. [2 marks](ii) Name another cell in X which has the same specialisation with cell P and Q. [1 mark](d) Explain why X is categorised as an organ.
