A cell in a prison is a small room where inmates are confined. It typically contains basic furnishings such as a bed, a toilet, and sometimes a small desk. Cells are designed to limit the movement of prisoners and ensure security within the facility. Cells are often grouped together in a larger area known as a cell block. Each cell usually has a door that can be locked, and some may have windows, though these are often barred or reinforced. The conditions in a cell can vary widely depending on the prison and its regulations.
