  1. January 10th, 2012 Daily Activity • Get out your packets. • Open to table in the middle of the packet and prepare to take notes. • FOR TODAY ONLY: Sit in the front 8 desks…if you mess up while in this formation, I will remove you from class. Today’s Agenda • Take notes on the cell, filling out your cell tables

  2. Cells • Cells are the basic unit of structure and function in all living things. • Many different types of cells but we will focus on Plant and Animal cells. • Contain smaller compartments called organelles which each have a specific function.

  3. Two Basic Cell Types 1) Prokaryote • Lacks internal compartments. • No true nucleus. • Most are single-celled (unicellular) organisms. • Examples: bacteria

  4. Two Basic Cell Types 2) Eukaryote • Has several internal structures (organelles). • True nucleus. • Either unicellular or multicellular. unicellular example: yeast multicellular examples: plants and animals

  5. Plasma Membrane • Also called the Cell Membrane. • Outermost portion of the cell. • Keeps all the pieces of the cell inside. • Characterization: Purse or human skin.

  6. Cilia • Fine, whip like/hair like structures that are on the outside of the cell. • Help the cell move and helps move liquid past the surface of the cell. • Characterization: Flippers

  7. Cytoplasm • Fluid that fills the cell. • Made of dissolved amino acids, sugars and fatty acids the cell uses to function. • Characterization: Filling of Ding Dong, Or the Jell-O in Raspberry Jell-O.

  8. Microfilaments • Long, thin, stringy proteins • Provide structure that helps the cell move, keep it’s shape, and move organelles • Helps form the cytoskeleton. • Characterization: Expansion Joints

  9. Microtubules • Thick, Strong fibers shaped like tubes. • Move vesicles, granules and other organelles • Important for cell division. • Characterization: Conveyor Belt

  10. Vesicles • Store or transport substances in and out of the cell. • Characterization: Mail Man

  11. Mitochondria • Provide the energy the cell needs to move, divide and contract. • Produces ATP = primary source of energy for the cell. • Characterization: Power Plant

  12. Vacuoles • Storage Bubbles. Store nutrients and wastes until they can get transported out of the cell. • Found mostly in plants, but also found in animals. • Characterization: Storage Bin, or a Water Jug

  13. Lysosome • Holds enzymes created by the cell. • Function is to digest things. • Work in low oxygen and pH zones • Characterization: Sewage Treatment Plant

  14. Peroxisome • Similar to Lysosomes, however they only dissolve things that are harmful to the cell. • Require oxygen rich environment. • Mostly break down Hydrogen Peroxide into water and Oxygen • Characterization: Police

  15. Ribosome • Used to produce proteins which are used as enzymes to support most functions of the cell. • Build chains of proteins, one amino acid at a time. • Characterization: Construction Workers

  16. Smooth Endoplasmic Reticulum • Network of membranes throughout the cell. • Looks like a bunch of tubes put together. • Important for storage within the cell. Usually stores steroids. Characterization: Storage Unit

  17. Rough Endoplasmic Reticulum • Synthesis and Packaging of proteins. • Looks like a bunch of tubes put together covered in ribosomes. Characterization: Packing Plant

  18. Golgi Apparatus/Body • Membrane Bound vesicle that packages microtubules for transportation elsewhere in the cell. • Builds Lysosomes • Characterization: Packaging Plant

  19. Nucleus • Contains the DNA of the cell. • Controls the eating, moving and reproduction of the cell. • Characterization: The Brain

  20. Chromosomes • Carry the genes of the cell. • Makes the cell what it is. • Characterization: The Brain

  21. Nucleolus • Produces Ribosomes • Characterization: Production Facility

  22. Plant Cells: Different Organelles • Cell Wall • Protective “box” around the plasma membrane and the cell. • Give the cell its shape • Allow plants to grow to great heights. • Characterization: Balloon in a cardboard box.

  23. Chloroplasts • Produce food for the cell. • Converts energy of the sun into sugars. • Characterization: Sugar Production Facility

  24. Vacuoles • Very Large • Hold water • A plant cell changes size depending on the amount of water present in the vacuole. • Characterization: Water Balloon

  25. Types of Solutions
