c) A student wanted to find out more about the cell cycle. The student made a slide of an onion root tip. She counted the number of cells in each stage of the cell cycle in one field of view. The table below shows the results.Stages in the cell cycleNon-dividing cells Stage 1 Stage 2 Stage 3 Stage 4 TotalNumber of cells209 4 2 1 36 Each stage of the cell cycle takes a different amount of time. Which stage is the fastest in the cell cycle? Give a reason for your answer.
