Document Summary
Organism - entity made up of one or more cells. Organisms share a suite of five fundamental characteristics: Information - organisms process hereditary, or genetic info. Energy - organisms require energy to survive. The five traits listed above laid out the groundwork for modern biology. Theory - an explanation for a very general class of phenomena or observations that are supported by a wide body of evidence. Robert hooke - discovered cells in a cork using a crude microscope. Anton van leeuwenhoek - made the first observation of single-celled organisms he named. Advances in microscopy have enabled the possibility to examine complexity of cells at higher and higher magnifications. Rudolph virchow - proposed that all cells arise from cells already in existence. (the complete cell theory builds on this concept: all organisms are made of cells and all cells come from preexisting cells. ) The cell theory was a direct challenge to the 1800s explanation of spontaneous.
