  1. The Amazing Animal cell!! “Hey, I thought cells were just for convicted cattle rustlers and horse thieves!”

  2. Why are Animal Cells so Amazing? CONVERT FOOD INTO ENERGY ADAPT TO OUTSIDE STIMULI

  3. Cells can determine: • How productive cattle will be. • How meat tastes! • Why animals get sick.

  4. CELLS CAN SPECIALIZE!! Nerve cell

  5. Amazing characteristics of cells! • They are the smallest unit of a living system. • They all hold the blueprints of how an animal is put together. c. They are vital to all life functions. d. They can reproduce!! e. They can change the physical form of an animal. Good traits and bad.

  6. There are basically two cell types Eukaryotic cells (membrane bound) Prokaryotic cells (before nucleus)

  7. A Prokaryote Cell • Single-celled organisms • Lacks internal structures • Example: Bacteria

  8. A Eukaryote Cell • Has internal membrane- bound structures called organelles. The largest organelle is the Nucleus, which contains the cell’s DNA. • May be made of one or many cells. • Makes up most of all living cells. Red blood cell

  9. How big are animal cells? 1 centimeter = 10 millimeters 1 millimeter = 1,000 micrometers

  10. Cell sizes range from 200 micrometers… pinhead

  11. 200 micrometers Human hair Pin head

  12. 200 micrometers Dust Mite

  13. 20 micrometers

  14. 20 micrometers Pollen grain Lymphocyte Red Blood Cell E-coli Bakers yeast

  15. 200 nanometers Ebola virus

  16. To 20 nanometers Rhinovirus

  17. How did scientists discover cells? • Using Microscopes!! • Instrument developed by 16th century Anton van Leeuwenhoek.

  18. CELL Theory states: • All organisms are composed of one or more cells. • The cell is the basic unit of organization of all organisms. • All cells come from pre-existing cells.

  19. Let’s go and look at somecells!! Step # 1 Teacher demonstration of microscope use. Step # 2 Students begin Microscope Lab 8.1 due today!!
