VIRUS & CELLS The Introductory level of Cells and Viruses By Mr. Hulscher 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 Virus Living or Non-living Living Non-living Doesn't adapt Reproduce only in cells called host cell Active destroy the host cell Latent "hides" Days, weeks, or years Doesn't eat Doesn't grow Viruses 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? 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 Main types of Cells Eukaryote – Multicellular organisms (mainly) Prokaryote – Unicellular organisms – Membrane bound structures – No membrane bound – All animals (you) – Most plants – Example: bacteria THE DISCOVERY OF CELLS Anton Von Leeuwenhoek Robert Hooke T. Schwann M. Schleiden THE DISCOVERY OF CELLS Anton Von Leuowonhook Robert Hooke T. Schwann M. Schleiden 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 THE DISCOVERY OF CELLS Discovered the first CELL - 1665 - in cork (dead cells) - named cells for the rooms monks live in THE DISCOVERY OF CELLS Discovered the first CELL - in PLANTS - helped with CELL THEORY THE DISCOVERY OF CELLS Discovered the first CELL - in ANIMALS - helped with CELL THEORY Cell Theory (as developed by many Scientists) 1) 2) 3) 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 Cellular Components Cytoplasm Nucleus Assigned terms. Plasma Membrane Nucleolus Cell Wall ASSIGNED TERMS Rough “ER” and Smooth “ER” Chromatin Explain 3 other types of Microscopes Organelles Fluid of the Cell The main component of organisms is water, this would be the cytoplasm. “Brain of the cell” Contains the blueprints of the activities “Hard drive or CPU of the computer” “Prison wall” Allows certain things in and certain things out. helps to maintain homeostasis (balance in the environment) “screen window” “Rigid structure or wall” Allows anything in and out. Found only in plants. Contains cellulose. The core of the Nucleus! Helps make ribosome's. RIBOSOMES - make proteins and enzymes with specific functions according to DNA 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 Energy, Structure, & Movement Mitochondria Cytoskeleton Chloroplasts Assignment A “POWERHOUSE” Transforms energy for the cell Where the cell gets its energy “GIVES THE SHELL SHAPE” Provides shape for the cell “tent poles” Converts light energy into mechanical Contains chlorophyll –CHLOROPHYLL - gives plants their green color Main Differences between Plants and Animal Cells Cell Wall (PLANTS) Vacuoles (Big In PLANTS) Chromatin (PLANTS) – Chlorophyll 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 The END!!! Study, I worked hard on this for YOU!!!
