1 fev 1802 ano - Lamarak and Dutrochet- all living things are composed of cells.

Descrição:

By the early 19t century the microscope become a standard tool of biologists, and living animal and plant cells were easy to observe. In the early 19th Century Jean Lamarak stated that all living things are a mass of cells, and that complex solutions move in and out of cells. Rene Dutrochet supported this idea, stating: 'plants are composed entirely of cells, or of organs that are obviously derived from cells... the same is true for animals.'
