Question

Henrietta Lacks was an African-American woman who died of cancer in Maryland in 1951. Before she died, some her cancer cells were recovered from a biopsy and grown in culture. After her death (and without prior consent from her or her family), these cells were widely used (and are still being used) by biomedical researchers because the cells grew indefinitely and prolifically, dividing every 24 hours. Before these cells (now known as HeLa cells) became available, scientists could not keep cultured human cells alive longer than a few days, which limited the types of investigations they could carry out. When grown in a dish, a typical HeLa cell has a diameter of about 20 μm, but it adheres to the surface, as most cells do, so that its shape is approximately a half-sphere . Estimate the cell volume in μL and pL.
