Visible, clear, well-defined patches in a monolayer of virus-infected cells in a culture are called plaques. This is a characteristic feature of a lytic viral infection, where the virus replicates, causes cell death, and spreads to adjacent cells in a culture dish. The areas of cell death form plaques, which can be used to quantify the number of infectious viral particles in a sample.
