1. Cells Basic Building Block of Life

2. Cell Theory 1)Cells are the basic units of structure & function in living organisms. 2)All living organisms are composed of 1 or more cells. a.Schleiden: all plants composed of cells b.Schwann: all animals composed of cells 3)All cells come from preexisting cells. a.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

9. Characterized Animal Cell

13. Blood Cell Types & Their Development

14. 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.

15. Cell membrane: Fluid mosaic model
