1.1. Figure 2 shows a bacterial cell and an animal cell as seen in a student’s textbook.

Figure 2

Animal cells store their genetic material in a nucleus, whereas a bacterial cell does not.

Give one other way in which a bacterial cell differs from an animal cell.

1.2. The cells in the diagram are drawn to a length of 100 mm in the student’s textbook.

The actual length of the animal cell is 60 micrometers (µm).

Calculate the magnification of the animal cell to 2 significant figures.

Show clearly how you work out your answer.

1.3. The nucleus of an animal cell has a diameter of about 6 µm.

Suggest a reason as to why bacteria do not have a nucleus.
