Cell Counting with Bower Counting Chamber

What is the size of one of the nine big squares on the Bower Counting Chamber slide?

• 4 x 4 millimeters

• 1 x 1 millimeter

• 2 x 2 millimeters

• 3 x 3 millimeters

Why might it be beneficial to dilute the cell sample before applying it to the counting chamber?

• To change the color of the cells

• To reduce the number of cells for easier counting

• To increase the number of cells

• To make the cells more visible

What is the typical volume of the sample applied to the Bower Counting Chamber?

• 5 microliters

• 10 microliters

• 15 microliters

• 20 microliters

Which cells are counted when they touch the boundaries of a square in the counting chamber?

• Cells touching the upper or left boundary

• Cells touching the lower or right boundary

• Cells not touching any boundary

• Cells touching any boundary

How is the total number of cells per milliliter calculated after counting?

• By adding the number of cells to the dilution factor

• By multiplying the number of cells by 10,000 and the dilution factor

• By dividing the number of cells by the dilution factor

• By multiplying the number of cells by 100
