Presentation Transcript

  1. Cells Basic Building Block of Life

  2. Cell Theory • Cells are the basic units of structure & function in living organisms. • All living organisms are composed of 1 or more cells. • Schleiden: all plants composed of cells • Schwann: all animals composed of cells • All cells come from preexisting cells. • Virchow contributed this.

  3. Prokaryotes • First life form: Archaea & Bacteria • Note cell wall & cytoplasmic membrane • No membrane-bound organelles • DNA in nucleoid • Ribosomes present • Errors in figure • Flagellum, singular • Cytosol

  4. Different Cell Types

  5. Eukaryotes • Protists, Fungi, Plants, & Animals • Have membrane-bound organelles • Nucleus with nucleolus • Endoplasmic reticulum: rough & smooth • Golgi apparatus • Mitochondrion • Chloroplasts, Chromoplasts, & other plastids • Vacuoles: plants’ 1 central vacuole; animals- many • Vesicles: lysosomes, peroxisomes, glyoxysomes

  6. Characterized Animal Cell

  7. Blood Cell Types & Their Development

  8. Things to know for the Exam • Cell types • Structure-function relationship • Form follows function. • Size varies greatly. • Organelles specific for animals vs. plants • Function of all organelles. • Plasma membrane structure & function.

  9. Cell membrane: Fluid mosaic model
