  2. CELL STRUCTURE AND FUNCTION contd. • 5. Cell Types • (a) Prokaryotic (b) (Eukaryotic) • 6. Cell Variety • 7. Description (viscuous; colloidal) • Cyclosis • 8.History (Hooke; Purkinje; Schleiden & Schwann)

  3. CELL ORGANELLES • 1. Plasma membrane • 2. Cell wall • 3. Endoplasmic reticulum (ER) • 4. Ribosomes • 5. Golgi Body • 6. Lysosome • 7. Vacuoles

  4. CELL ORGANELLES contd. • 8. Microbodies • 9. Mitochondria • 10. Chloroplast • 11. Centrioles • 12. Cilia & Flagella • 13. Nucleus & Nucleolus • Chromosomes

  5. CELL STRUCTURE & FUNCTION contd.{Cell Permeability} • I. Molecules that become incorporated into cells without going through the cell wall. • A. Pinocytosis • B. Phagocytosis • II. Molecules that become incorporated into cell by passing through the wall.
