Question 16
Easy

A student used a light microscope to observe a slide of a growing garlic root tip. They counted a total of 94 cells. The table below shows the number of cells observed at each stage of the cell cycle.

Stage of cell cycleNumber of cells
Interphase58
Prophase11
Metaphase7
Anaphase13
Telophase5

Use the following equation to calculate the mitotic index for this slide.

mitotic index=number of cells in mitosistotal number of cells×100 \text{mitotic index} = \frac{\text{number of cells in mitosis}}{\text{total number of cells}} \times 100 mitotic index=total number of cellsnumber of cells in mitosis​×100

Give your answer to three significant figures.
