  1. Cell Theory History is Fun! Theories are less fun… Ugh and organelles…this gets worse andworse andworseandworse….

  2. The Discovery of Cells • What is this junk anyway??? • Well 1st we need to know what is a CELL? Well of course its the smallest unit that can carry on all of life processes…duh • Why are they important? • They let us know if things are living or not • Some organisms are only one cell, but still very important despite their size • And best of all…They are pretty to look at!

  3. Well who the devil started this mess??? • Robert Hooke- He invented the light microscope with magnifying lenses and light rays. • What did he see? “a great many little boxes” that reminded him of cubicles or “cells” where his monk friends lived… COZY  H O T T I E !!!

  4. The other Hook… • Anton van Leeuwenhoek- sweet name buddy!!! • He rocks because he is the 1st person to ever see LIVING cells! • He made tiny little baby microscopes for him and his friends to play with on Friday nights b/c video games weren’t a big thing back then. • These microscopes had about a 10x magnification and it opened up a whole new world!!!!

  5. And the Plot thickens… • Matthias Schlieden- German dude who said all plants have cells • Theodor Schwann- Another German dude that hates the previous German dude and said all animals have cells • Rudolf Virchow- A third German dude that is a doctor so who cares… and said cells come from cells • Ver+ Put it all together and what do you got? CELL THEORY!!!! • All living organisms have one or more cells • Cells are the basic structure and function in an organism • Cells only come from cells

  6. Basic Parts • Plasma Membrane- the cells outer boundary…acts as a barrier • Cytoplasm- the nasty fluidy stuff in a cell. It holds all the organs together… kinda like jello  • Control Center- Cells have to have DNA in them in some way shape form or fashion…usually in a NUCLEUS…the brain of the cell.

  7. Two Major Types • Prokaryotes • Organism without membrane wrapped parts called organelles • They don’t have a nucleus so their DNA is concentrated and hangs out together in a little ball. • Examples- Bacteria!!! • Eukaryotes • Have membrane bound organelles • These organelles have specific jobs that they do in the cell • Examples- everybody else!
