The Cell: Discovering the Cell

The video discusses the use of simple microscopes by early scientists like Robert Hooke and Anton Van Leeuwenhoek. Hooke observed cork under a microscope in 1663, discovering structures he named 'cells', which were actually the cell walls of dead plant cells. Around the same time, Leeuwenhoek used a simple microscope to discover single-celled organisms, now known as bacteria.
