  • 1. Cell Biology! http://www.mybloodyourblood.org/biology_white.htm http://publications.nigms.nih.gov/insidethecell/chapter3.htmlhttp://stemcelldaily.com/stem-cells-are-purdy-pics/ jschmied©2015
  • 2. Cell Biology Learning Goals A. Microscopy • I can properly use and maintain a Compound Light Microscope AND tell the names & functions of its parts . B. Cells Identification & Organelles • I can explain the key similarities & differences & Plant and Animal cells. C. Characteristics of Living Things • I am able to describe the characteristics that make something “living.” D. Photosynthesis & Respiration in Cells • I can trace key components of life (O2, Food, Water) into & out of plant & animal cells. (Onion, Elodea, Amoeba, Cheek Cells) D. Experimenting: • I can test & analyze yeast samples to demonstrate that cells respire. jschmied©2015
  • 3. jschmied©2015 Cell Biology Performance Expectations
  • 4. Vocabulary: Bacteria Single-celled organisms without a nucleus or other membrane-bound organelles. Cell - The smallest structural unit enclosed by a membrane. These make up all living organisms. Cell Membrane: - The semipermeable double membrane surrounding the cytoplasm of a cell. Semi permeable => lets some things in & out, but not others. Cellular respiration - The process of breaking down food to produce energy for a cell. Takes place in the cell’s mitochondria. – The formula is: Sugar (glucose) + O2 CO2 + H2O + Thermal Energy Cell theory - A basic theory of biology which states: – All living things are made up of cells. – All new cells are made from existing cells. – Cells are the basic units of structure and function in living organisms Cell Wall: - Rigid outer coating of a typical plant, bacteria or fungi cell. Main uses: protection, structural support, & semi permeable (lets some things in & out, but not others) Chloroplast: Plant Organelle contains chlorophyll. Inside the chloroplast Sunlight + CO2 + H20 is combined to make Sugar + O2 Cilia - tiny, hairlike structures used by cells to provide mobility (move). Cytoplasm - Gel like fluid that fills a cell. Mainly water, salts and proteins. Disease - An abnormal condition affecting all, or part of, an organism Flagella - a slender whip like structure that allows cells to move. (Found in Plants, Animals, Protist & Fungi.) jschmied©2015
  • 5. Vocabulary Part 2: Germ theory of disease - This theory states some diseases are caused by microorganisms or “germs” Infectious - A disease that is passed from one organism to another. Microbe - Any microscopic cell or virus. Especially applied to disease causing bacteria. Magnify, magnification - To enlarge an image of an object, The amount an object is enlarged. Mitochondria – Cell organelle that chemically breaks down sugar (glucose) to chemical energy for use by the cell. Found in both plant and animal cells. The process is: Sugar (glucose) + O2 CO2 + H2O + Thermal Energy Multicellular - An organism made up of many cells, each specialized to do a task (muscle cell). Nucleus – Organelle within a cell containing the majority of the cell’s DNA. Nuclear membrane - The membrane separating the nucleus from the rest of the cell. Organelles - Parts within a cell that perform specialized functions like organs do. (breaking down sugar, digestion, moving proteins, photosynthesis, making DNA etc) Photosynthesis - Process used by plants (& some other organisms) to convert light energy with CO2 + H2O into chemical energy. Takes places in a cell’s chloroplasts. Formula is: CO2 + H2O + Sunlight  Sugar + O2 Protist – Organism made up of single, or multiple cells, with a nucleus. Not an animal, plant, or fungus. Unicellular Organism– A single cell organism which does all life processes. (Protist, Algae etc.) Virus – A very small microbe, not a cell, that can only grow or reproduce inside of a living cell. jschmied©2015
  • 6. The modern Cell Theory 1. All living organisms are made up of one or more cells. 2. All living cells come from preexisting cells by division. 3. The cell is the basic unit of structure & function in all living organisms. 4. Energy flow occurs in cells 5. Cells contain heredity info (DNA) that is passed to other cells during Cell Division 6. The activity of an organism depends on the total activity of its independent cells. I am able to explain why cells are the fundamental unit of all life. (The Cell Theory) jschmied©2014
  • 7. Cell Respiration – Animal & Plant O2 + Glucose (C6H12O6) CO2 + H2O + Waste + T Energy Lungs Small Intestine Lungs Kidneys Mitochondria Chemical Energy   Energy for the rest of the cell Mitochondria Waste Heat I can trace key components of life (O2, Food, Water) into & out of plant & animal cells w/Insulin jschmied©2014

  • 9. Photosynthesis Plants & some Bacteria Mitochondria converts glucose into Chemical Energy Via Cell Respiration  O2 + Glucose (C6H12O6) In Chloroplast CO2 + H2O Air Roots & Air I can trace key components of life (O2, Food, Water) into & out of plant & animal cells Out Vacuole Storage jschmied©2014

Gel like material in cell. Breaks down nutrients from food & builds new substances to grow or carry out cell functions cell organelle that chemically breaks down sugar (glucose) with O2 to make chemical energy for the cell. Organelle within a cell containing the majority of the cell’s DNA. (DNA) directs cell activities. Separates the nucleus from the rest of the cell. jschmied©2015 All but Bacteria Perform specialized cell functions (Mitochondria, Chloroplast, Nucleus… a. Obtain & store energy b. Help cells move & divide, c. Make substances used in cell or transported to other parts of the body.
