Cell Density - Definition, Glossary, Details - Oilgae
The density of a material is defined as its mass per unit volume:
Rho = m/V
Different materials usually have different densities, so density is an important concept regarding buoyancy, metal purity and packaging.
Cell density refers to the number of cells per unit volume. Often cell density is denoted as viable cell density which is the number of living cells per unit volume.
