Document Summary

Matthias schleiden (1838-botanist) =believed that even though there are distinctive tissues, plants consisted of cells and that it arose from a single cell. Theodor schwann (colleague of schleiden and a german zoologist, 1839) = published a report stating that cells of plants and animals are the same in structure and came up the 2theories. Cells are the structural unit of life (they make up a tissue then an organ then the human being) Rudolf virchow (1855) = german pathologist, came up with the third cell theory (tenant) Cells arrive or become through division of pre-existing cells. = the director of what goes on in the cell. Because of the genes molecular structure, this can allow the www. notesolution. com genes creates biological evolution. : transcription of genes from dna to translation of rna to create protein (genes to proteins) to mutate and can create variations of organism, which. Information to build a cell is in a gene.
