  1. HISTORY OF CELL DISCOVERY Late 1600s 1500s Early 1600s 1665 1830s Rudolph Virchow: Looked at Invented 1) 2) Zoologist that said: Botanist that said: and called them • The cell is the basic unit of life • Anton Van Leeuwenhoek • Hans & Zaccharias Janssen • Pond water • MatthaisSchleidan • All living things are made of 1+ cells • Plants are made of cells • Cells Also looked at Leads to Cell Theory: 1) 2) 3) And called the swimming microbes: • Theordor Schwann • All cells come from pre-existing cells • Used hand lenses to assess cloth quality • Robert Hooke • High quality lenses • First light microscope • “Animalcules” • Physician that studied cancer • Thin slices of cork • Invented 1st crude microscope • Animals are made of cells

  2. Word Bank • No nucleus • Molecules • Has Membrane-bound organelles • Word Bank • Animals • Plants • Fungi • Protists • Simple • Complex • Evolved first • Evolved later • Bacteria CELL TYPES • Prokaryote • Has Nucleus • Eukaryote Cells fall into two basic categories: • No membrane-bound organelles Have the following basic characteristics: Have the following basic characteristics: Example (1): 1) 2) 3) 4) 1) 2) 3) 4) Examples (4): Can

  3. COMPARE PLANT, ANIMAL, AND PROKARYOTIC CELLS PLANT CELLS ANIMAL CELLS • Flagella • Lysosomes • DNA • Nucleus/Nucleolus/Nuclear Membrane • Ribosomes • Cytoplasm • Cell Membrane • Cell Wall • Vesicles • Large Central Vacuole • Mitochondria • Cilia • Chloroplasts • Golgi Apparatus • Centrioles • Rough & Smooth ER • Capsule • Pili PROKARYOTE CELLS

  4. CELL ORGANIZATION < < < < LARGEST created by joining cells that have similar function or structure group of tissues that perform a specific function or groups of functions collection of organs that perform a specific function Basic unit of life, stated in Cell Theory Unicellular means: Multicellular Means: • Word Bank: • Organism • Tissue • One-cell • Organ • Cell • Circulatory System • Red Blood Cell • “Many cells” • Heart • Human • Epithelial Tissue Less complex on individual level; specialized perform diff. tasks More complex on individual level; perform all life functions Example organization: < < < <

  5. LABEL THIS ANIMAL CELL: • Word Bank: • Mitochondria • Ribosomes • Vacuole • Golgi Apparatus • Cyotplasm • Cell Membrane • Nuclear Membrane • Nucleus • Nucleolus • Endoplasmic Reticulum • Site where DNA is found • Vesicle

  6. LABEL THIS PLANT CELL: • Word Bank: • Mitochondria • Ribosomes • Central Vacuole • Golgi Apparatus • Cytoplasm • Chloroplast • Cell Membrane • Nuclear Membrane • Nucleus • Nucleolus • Cell Wall • Endoplasmic Reticulum • Site where DNA is found
