Final answer:
To calculate the percentage that each cell in a column contributes to the whole, divide the number of that cell type by the total number of cells observed and multiply by 100.
Step-by-step explanation:
To calculate the percentage that each cell in a column contributes to the whole, you need to divide the number of that cell type by the total number of cells observed and multiply by 100. For example, if there were 50 cells of a certain type and a total of 100 cells observed, the percentage would be (50/100) * 100 = 50%. Repeat this calculation for each cell type in the column to determine the percentage contribution of each.
