Transcript

  • 1. 3.00 vocabulary All about cell theory and cells!!!
  • 2. Microscopes Technology that is used to see tiny objects Electron microscopes are the most powerful microscopes today Anton van Leeuwenhoek Robert Hooke Van Leeuwenhoek, a Dutch lens maker, used a homemade microscope to look at some pond scum He was the first person to see single celled organisms. He called them “animalcules” In 1665, Hooke, an English scientist, used a microscope he had built to study a thin slice of cork He saw the outer layers of the piece of cork’s cell walls He called the structures he saw “CELLS,” which means little rooms in Latin
  • 3. Matthias Schleiden Theodor Schwann Rudolf Virchow German botanist Looked at MANY slides of plant tissues In 1838, concluded that all plants are made of cells German scientist Studied animals Observed many different kinds of cells. In 1839, stated that all animal tissues are made of cells German doctor In 1858, concluded that all cells developed from other cells
  • 4. Write all of this!! The Cell Theory 1. All living things are made of one or more cells. 2. The cell is the basic unit of structure and of function in all living things. 3. All cells come from other living cells.
  • 5. Lipids: Monomer: monosaccharide: Nucleic Acid: Enzymes: Fats and oils. Composed of carbon and hydrogen. They are used to store energy long term. Examples: butter, vegetable oil, found in cell membranes. Smallest building block of a macromolecule. Used to make other molecules. For example: glucose and fructose are monomers of carbohydrates. Glucose + Fructose together make sucrose. Simple sugars. Glucose and fructose are examples. Larger sugars are made by combining the simple sugars together. Composed of carbon, hydrogen, oxygen, nitrogen, and phosphorous. Building blocks of DNA & RNA. Used to store the genetic information of the cell. Ex: DNA & RNA. A protein that increases the rate at which chemical reactions. The enzyme does not change.
  • 6. Proteins: Polysaccharide: Disaccharide: Polymer: Carbohydrate: Composed of hydrogen, oxygen, carbon, and nitrogen, and sulfur. Building blocks of amino acids. Examples: muscles in body, collogen in skin, hemoglobin in blood. Many simple sugars in very long chains. Create molecules to be used for long-term energy storage. Examples: glycogen & cellulose Two simple sugars joined together. Glucose + Fructose = Sucrose. Long chains of monomers stuck together. Molecules made up of carbon, hydrogen, and oxygen. They provide energy for living things. Examples: glucose, sucrose, cellulose.
  • 7. Prokaryotic Cells Eukaryotic Cells 1. No nucleus 1. Nucleus 2. No membrane covered organelles 2. Membrane covered organelles 3. Circular DNA 3. Linear DNA (line) 4. Examples: Bacteria! Draw picture!!!! 4. Examples: Every other type of cell: animal, plant fungus, protist
  • 8. Animal Cell Cytoplasm Nucleolus Nucleus Ribosomes Cell Membrane Mitochondria Rough Endoplasmic Reticulum Golgi Bodies Smooth Endoplasmic Reticulum
  • 9. Plant Cell Cytoplasm Vacuole Smooth ER Ribosomes Chloroplasts Cell Membrane Cell Wall Nucleolus Golgi Bodies Nucleus Mitochondria Rough ER
  • 10. Nucleus Ribosomes Endoplasmic Reticulum (ER) Lysosomes: Mitochondria Nickname: “The Control Center” Function: holds the DNA Parts: Nucleolus: dark spot in the middle of the nucleus that helps make ribosomes Function: makes proteins Found in all cells, prokaryotic and eukaryotic Nickname: “Roads” Function: The internal delivery system of the cell Nickname: “Clean-up Crews” Function: to break down food into particles the rest of the cell can use and to destroy old cells Nickname: “The Powerhouse” Function: Energy formation Breaks down food to make ATP ATP: is the major fuel for all cell activities that require energy
  • 11. Vacuoles Chloroplasts Cell Wall Function: stores water This is what makes lettuce crisp: When there is no water, the plant wilts Function: traps energy from the sun to produce food for the plant cell Green in color because of chlorophyll, which is a green pigment Function: provides support and protection to the cell membrane Found outside the cell membrane in plant cells These three organelles are ONLY FOUND IN PLANT CELLS
