Presentation Transcript

  1. CELLS Structure and Function Cell = smallest unit of life

  2. Two Major Cell Types

  3. Prokaryotic Cell

  4. Eukaryotic Cell (protist, animal)

  5. Eukaryotic Cell (plant)

  6. Components Common to All Cells • Plasma Membrane boundary surrounding the cell • Genetic material: DNA found in one or more chromosomes • Cytoplasm Fluid containing enzymes and organelles

  7. Differences Between Cell Types

  8. Features of All Prokaryotic Cells

  9. Features of SomeProkaryotic Cells

  10. Features of SomeProkaryotic Cells

  11. Which feature is unique to prokaryotic cells? Which feature is unique to eukaryotic cells? Which feature(s) do prokaryotic and eukaryotic cells have in common? Nucleus Ribosome Capsule Cytoplasm Nucleoid Applying Your Knowledge

  12. Features of Eukaryotic Cells

  13. Features of Eukaryotic Cells

  14. Motion of cilia and flagella

  15. Features of Eukaryotic Cells

  16. Features of Eukaryotic Cells

  17. Eukaryotic Cell Nucleus DNA + protein = chromatin Chromosomes are composed of chromatin. Chromatin appears diffuse during most of the cell cycle.

  18. Features of Eukaryotic Cells

  19. Features of Eukaryotic Cells

  20. Rough Endoplasmic Reticulum

  21. Features of Eukaryotic Cells

  22. Features of Eukaryotic Cells

  23. Features of Eukaryotic Cells

  24. Features of Eukaryotic Cells

  25. Which organelle produces proteins that will be exported from the cell? Which organelle contains digestive enzymes? Which site acts as a protein packaging and distribution center? Cilium Rough ER Golgi apparatus Smooth ER Lysosome Applying Your Knowledge

  26. Features of Eukaryotic Cells

  27. Features of Eukaryotic Cells

  28. Features of Eukaryotic Cells

  29. Thought Questions • What are similarities for a. eukaryotic and prokaryotic cells? b. animal and plant cells? 2. What are differences between a. eukaryotic and prokaryotic cells? b. animal and plant cells?
