Cells as the basic units of living organisms — practice question

Four students had to pair each function with the correct appearance of certain cell structures in an animal cell. The functions were numbered as follows: (1) forms the mitotic spindle during cell division; (2) makes polypeptides; (3) makes lipids. The appearances were labelled by letter: V membranes enclosing an inner cavity; W spherical structures not bounded by a membrane; X a double membrane with pores spaced through it; Y cylindrical structures not bounded by a membrane; Z membrane-bound sacs arranged in a flattened stack. Which student matched the numbered functions to the appearance of the cell structure correctly?

  • A1 W, 2 X, 3 Z
  • B1 W, 2 Z, 3 V
  • C1 Y, 2 W, 3 V
  • D1 Y, 2 Z, 3 W
