He called what he saw "animacules".]]> 2021-11-23 17:06:23 UTC https://padlet.com/student142118/biology/wish/1908908383 student142118 https://padlet.com/student142118/biology/wish/1908912605 While observing cork through his microscope on 1665, Hooke saw tiny boxlike cavities, which he illustrated and described as cells. He had discovered plant cells! Hooke's discovery led to the understanding of cells as the smallest units of life—the foundation of cell theory.]]> 2021-11-23 17:08:31 UTC https://padlet.com/student142118/biology/wish/1908912605 student142118 https://padlet.com/student142118/biology/wish/1908919085 In 1838 Schleiden defined the cell as the basic unit of plant structure.]]> 2021-11-23 17:11:43 UTC https://padlet.com/student142118/biology/wish/1908919085 student142118 https://padlet.com/student142118/biology/wish/1908923825 In 1838 Schwann defined the cell as the basic unit of animal structure.
In 1839 concluded that all tissues are made up of cells: this laid the foundations for the cell theory.]]> 2021-11-23 17:13:53 UTC https://padlet.com/student142118/biology/wish/1908923825 student142118 https://padlet.com/student142118/biology/wish/1908927715 Virchow's cellular theory was encapsulated in the epigram Omnis cellula e cellula ("all cells (come) from cells"), which he published in 1855. ]]> 2021-11-23 17:15:49 UTC https://padlet.com/student142118/biology/wish/1908927715
