In human bodies, nearly two trillion cells divide every day. Watch cells divide in this time lapse video of an animal cell (top) and an E. coli bacteria cell (bottom). The video compresses 30 hours of mitotic cell division into a few seconds. Multicellularity allows an organism to exceed the size limits normally imposed by diffusion: single cells with increased size have a decreased surface-to-volume ratio and have difficulty absorbing sufficient nutrients and transporting them throughout the cell. Multicellular organisms thus have the competitive advantages of an increase in size without its limitations. They can have longer lifespans as they can continue living when individual cells die. Multicellularity also permits incre… danbury hospital blood lab hours
