  6. The Cell Theory

  7. 1.The Fundamental Unit of Life is the Cell • Every living organism has at least one • One cell = Unicellular • Cell = the body • More than one cell = Multicellular • Cells have specific functions

  8. Euglenaone cell = unicellular

  9. Amoeba one cell = unicellular

  10. Bacteriaone cell = unicellular

  11. Kittenmore than one cell= multicellular

  12. Daphniamore than one cell =multicellular

  13. Flowermore than one cell = multicellular

  14. 2. Cells carry out the functions needed to support life • Unicellular : the cell is the body • Takes in food gets rid of waste • Asexually reproduces (clones itself) • Multicellular: each cell serves a specific function • Blood cell • Nerve cell • Muscle cell

  15. Kittens have blood cells

  16. Kittens have nerve cells

  17. Kittens have muscle cells

  18. Daphnia have egg cells

  19. Lily pads have cells that make transport tissue (like our blood vessels)

  20. Lily pads have leaf cells

  21. 3. Cells come only from other living cells • Cells are constantly making copies of themselves • Mitosis: body cells like skin and muscle • Meiosis: sex cells (sperm and egg) • Binary fission: bacteria and some unicellular organisms • Budding: some unicellular organisms like bakers yeast

  22. 3. Cells come only from other living cells Body Cells like skin cells and muscle cells

  23. 3. Cells come only from other living cells Ecoli Bacteria and Binary Fission

  24. 3. Cells come only from other living cells Unicellular organism going through binary fission

  25. 3. Cells come only from other living cells Bakers Yeast budding

  26. Cell Theory • 1.The Fundamental Unit of Life is the Cell • 2. Cells carry out the functions needed to support life • 3. Cells come only from other living cells • Unicellular= One cell= body cell • Multicellular= More than one cell= cells have specific functions
