Four students were asked to match the function with the appearance of some cell structures in an animal cell.
The functions were listed by a number.

1) organises microtubules to produce the spindle during cell division
2) synthesis of polypeptides
3) packaging of hydrolytic enzymes that will remain in the cell

The appearances were listed by a letter.

V- membranes which surround an enclosed inner cavity
W- non-membrane bound, spherical structures
X- a double membrane with many pores
Y- non-membrane bound, cylindrical structures
Z- membrane-bound sacs, arranged as a flattened stack

Which student correctly matched the numbered function with the appearance of the cell structure?
