In the 1830"s the compound microscope was made. Noticed that every plant cell contained a round structure he called a kernel" but. Allowed visualization of objects less than 1 m. All plant tissue are composed of cells. Embryonic plant always come from a single cell. He recognized the structural similarities between plants and animals. All organisms consist of one or more cells. The cell is the basic unit of structure for all organisms. All cells are made by the division of pre existing cells. An attempt to state our best current understanding based on observation and experiments. Valid only until revised and replaced by a better understanding based on more careful observation or more discriminating experiments.
