  2. TheCell • We’lldiscover: • Thedifferentparts of thecell and theirfunctions. • Howcellsmake new cells.

  3. Multicellular • Eachcellperformsspecializedjobs. • Unicellular • Onecelldoesallthejobs. Human Bacteria Animal

  4. THE CELL THEORY • All living things are made • of oneor more cells. • Cells are the basic unit • of living things. • All cells come from • existingcells.

  5. 1663-Robert Hookediscovers cells • 1831-Robert Brown discovers the cell • nucleus • 1838-Matthias ShleidenproposestheCell • Theory • 1857-Albrecht von Köllikerfinds • mitochondria in muscle cells • 1865-Julius von Sachs shows that • chlorophyllislocated in chloroplasts • 1931-Ernst Ruska & Max Knollinventsthe • electronmicroscope • 1953-George E. Palade describes ribosomes
