Cell shapes: spherical

Cells that are in a fluid environment, e.g., blood, usually take on a spherical shape. In this blood smear, white blood cells are spherical. The red blood cells, in contrast, are bi-concave discs, which afford greater surface area for exchange of gases across the cell membrane. 1000x
