  1. GREEN TEST Nucleus Endoplasmic reticulum Cell membrane RED TEST mitochondria Vacuole Cell wall List the function of each organelle

  2. Things to find out about cells • What shape do most cells have? • How many nuclear membrane layers? Why? • What produces energy in a cell? • How does water get into a cell? • How does CO2 get out of a cell? • What does a nucleus do? • What does the endoplasmic reticulum do? Look like?

  3. White Board Answers • Group 1: Questions 1 & 6 • Group 2: Questions 2 & 4 • Group 3: Questions 3 & 2 • Group 4: Questions 4 & 1 • Group 5: Questions 5 & 3 • Group 6: Questions 6 & 5

  4. Cell history • Leeuenhoek • Hooke • Schwann • Schleidan Contempories; 1730’s German sci; credited w/ the idea of cell theory; the beg of the end of spontaneous generation

  5. Beg Microscopes http://en.wikipedia.org/wiki/File:Leeuwenhoek_Microscope.png http://chem.aellumis.org/wp-content/uploads/2013/08/hookes_microscope.jpg

  6. Prokaryotic “simple” no nucleus or membrane bound organelles most have cell wall All are bacteria of some type Eukaryotic Have nucleus* and membrane bound organelles More diverse Only plant and fungi have cell walls Two Types of Cells

  7. Generalized Bacteria Cell

  8. List of Organelles w/ Membranes Cell Membrane: Nucleus: nucleolus Mitochondria: Chloroplast: Vacuole:

  9. Cell membrane

  10. Cytomembrane Organelles • Endoplasmic Reticulum (ER): • rough • smooth • Golgi Body: • Lysosomes/peroxisomes:

  11. Generalized cell for cytomembrane system

  12. Other Organelles • Ribosomes • Centrioles • Cytoskeleton • microtubules • microfilaments

  13. Other Organelles, cont • Cytoplasm/cytosol • Cell wall • slime capsule • Cilia/flagella

  14. Organelle Assignment • 5 Cinquain poems • Noun • 2 adjectives • 3 verbs to describe organelle • 4 word phrase • 1 noun synonym

  15. W/out nrg = Passive Osmosis: Diffusion: Facilitated Diffusion: With energy Active transport: Bulk transport: endocytosis exocytosis How substances enter cell (ch 5)
