Document Summary
What is a cell: atoms -> molecules -> macromolecules -> organelles. , cell -> tissues -> organism -> community: sub particles of eukaryotes and prokaryotes.

Anton van leeuwenhoek (1674) examined pond water under a modified hooke microscope and called what he observed. Matthias schleiden (1838), theodor schwann (1839) & rudolf virchow (1855: proposed the cell theory: All organisms are composed of one or more cells: the cell is the structural & functional unit of life, cells can arise only by division from a preexisting cell. Basic properties of cells: cells are highly complex and organized, cells possess a genetic program and the means to use it. Genes ultimately code for proteins: cells are capable of producing more of themselves. Mitosis and meiosos: cells can acquire and utilize energy.
