(1)
(e) The cheek cell in Figure 2 is magnified 250 times.
The width of the cell is shown by the line D to E.
Figure 2
Calculate the width of the cheek cell in micrometres (µm).
Complete the following steps.
Measure the width of the cell using a ruler .......................................... mm
Use the equation to work out the real width of the cell in mm:
real size = ............................................ mm
Convert mm to µm ............................................. µm
(3)
(f) A red blood cell is 8 µin diameter.
A bacterial cell is 40 times smaller.
Calculate the diameter of the bacterial cell.
