VIRUS & CELLS

1. VIRUS & CELLS The Introductory level of Cells and Viruses By Mr. Hulscher

2. OUTLOOK & REVIEW!!! • Understand the function of the cell • Understand the abilities of a virus • Explain types of viruses and cures • Explain the two main basic types of cells • Distinguish among the scientists • Describe organelles of the cell • Relate the difference between plant and animal cells

3. VirusLiving or Non-living

4. No Cure for Viruses Vaccine prevent the virus Actually dead or weak forms of the disease Edward Jenner (1796) discovered vaccine for smallpox Cold sore, cold, AIDS, mumps, measles, Chicken Pox Gene Therapy finds cure for bad gene (sickle cell anemia) AIDS (HIV) Attacks the immune system No Cure Die from it? Viruses

5. Cells(basic unit of a living organism) • Carry out the functions within the system • Nerve, White BC, RBC, muscle, epithelial, etc. • 1000’s of different types of cells

6. Eukaryote Multicellular organisms (mainly) Membrane bound structures All animals (you) Most plants Prokaryote Unicellular organisms No membrane bound Example: bacteria Main types of Cells

7. THE DISCOVERY OF CELLS Anton Von Leeuwenhoek Robert Hooke T. Schwann M. Schleiden

8. THE DISCOVERY OF CELLS Anton Von Leuowonhook Robert Hooke T. Schwann M. Schleiden

9. THE DISCOVERY OF CELLS Discovered the first microscope (simple light microscope 270 X’s) Compound light microscope - uses more than one lens - mainly used today by us

10. THE DISCOVERY OF CELLS Discovered the first CELL - 1665 - in cork (dead cells) - named cells for the rooms monks live in

11. THE DISCOVERY OF CELLS Discovered the first CELL - in PLANTS - helped with CELL THEORY

12. THE DISCOVERY OF CELLS Discovered the first CELL - in ANIMALS - helped with CELL THEORY

13. Cell Theory(as developed by many Scientists) • All organisms are composed of one or more cells • A cell is a basic unit of organization of all organisms • All cells come from pre-existing cells

14. Cellular Components

15. ASSIGNED TERMS • Rough “ER” and Smooth “ER” • Chromatin • Explain 3 other types of Microscopes • Organelles

16. Fluid of the Cell The main component of organisms is water, this would be the cytoplasm.

17. “Brain of the cell” Contains the blueprints of the activities “Hard drive or CPU of the computer”

18. “Prison wall” Allows certain things in and certain things out. helps to maintain homeostasis (balance in the environment) “screen window”

19. “Rigid structure or wall” Allows anything in and out. Found only in plants. Contains cellulose.

20. The core of the Nucleus! Helps make ribosome's. RIBOSOMES - make proteins and enzymes with specific functions according to DNA

21. ASSEMBLY, TRANSPORT, STORAGE • Endoplasmic Reticulum • “factory” where the work area is • Golgi Apparatus • “packaging” gets the proteins ready • Vacuoles • “storage” enzymes, food, and cell materials • Lysosomes • “recycler” digests worn out or extra organelles, food, and viruses or bacteria

22. Energy, Structure, & Movement

23. “POWERHOUSE” Transforms energy for the cell Where the cell gets its energy

24. “GIVES THE SHELL SHAPE” Provides shape for the cell “tent poles”

25. Converts light energy into mechanical • Contains chlorophyll • CHLOROPHYLL - gives plants their green color

26. Main Differences between Plants and Animal Cells • Cell Wall (PLANTS) • Vacuoles (Big In PLANTS) • Chromatin(PLANTS) • Chlorophyll

27. Multi-cellular Organisms • Cells are grouped into TISSUES • TISSUES are grouped into ORGANS • ORGANS are grouped into ORGAN SYSTEM • ORGAN SYSTEMS are grouped into ORGANISMS

28. The END!!!Study, I worked hard on this for YOU!!!
