Any two-dimensional image of a cell is technically a cross section.
Cell
white blood cells are a whitey Grey ball with furry spikes
will the readings of the load cell differ from the above if it is placed at 100 mm from the center of the cross section
10% of white in our body
The center of a red blood cell appears paler than the outer part because of how the cell is shaped. The red blood cell has a biconcave shape that is fat at the edges and flattened in the center, giving it a cross section that resembles a dumbbell.
check the microscope and the cross section views....
