  4. $30 Microscopes (3) • What type of microscope would view an organism 2500 X’s and its internal structures? • Type of microscope to view atoms? • Who made the first microscope? • ANSWER: TEM • SPM • Leeuvenhoek

  5. $40 Microscopes • What term means “clarity, or being able to distinguish two objects as separate?” • What term means the objectives will stay in focus if you just turn the revolving nosepiece? • ANSWER: resolution (or resolving power) • parfocal

  6. $50 Microscopes • What is the size of this organism? (mm + µm) What is the field diameter? • ANSWER: 0.5 mm or 500 µm • F.D. = 1.5 mm

  7. OSMOSIS APPLICATION • Go back to your lab table and look at the potatoes. Write answer to question #3. (Which is crisp and which is saggy?)

  8. $60 Microscope • Describe how to prepare a wet mount: (pic next slide) • ANSWER: 1. object on slide • 2. Drop of water on slide • 3. Cover slip on water and object.

  9. Wet Mount

  10. $70 Microscopes • Show where these are on a compound light microscope:stage • Condenser • Iris diaphragm • Coarse adjustment • Fine adjustment

  11. $10 Nicknames • What organelle would be known as “the genetic control center?” • ANSWER: nucleus

  12. SNEAKER: WHAT DOES • “in equilibrium” mean? • ANSWER: concentration of solute is the same throughout the solution

  13. $20 Nicknames (2) • What organelle is the powerhouse of the cell? • What structure of the plasma membrane is for identification markers? • ANSWER: mitochondrion • ANSWER: carbohydrate chains

  14. $30 Nicknames (3) • What could be called the “ribosome factory?” • What is the name of movment in and out of the plasma membrane that uses ATP? • Do prokaryotes contain membraned-bound organelles like eukaryotes? • ANSWER: nucleolus • ANSWER: active transport • ANSWER: no

  15. $40 Nicknames (2) • What organelle means “network of channels within a cell?” • What are two other names for the cell membrane? • ANSWER: Endoplasmic reticulum • ANSWER: plasma membrane Phospholipid bilayer

  16. $50 Nicknames (2) • What organelle means “breakdown body” or “clean-up crew?” • How is osmosis and diffusion different? • ANSWER: lysosome • ANSWER: osmosis is water moving through a selectively permeable membrane

  17. $60 Nicknames(2) • What could be called ”pita bread shaped warehouse and finishing factory?” • Describe “receptor-mediated endocytosis.” • ANSWER: Golgi apparatus • ANSWER: indentation of plasma membrane has receptors that fill and fall into the cytoplasm as a food vacuole

  18. $70 Nicknames • What would be called in a cell:(A) the supportive meshwork of fine fibers AND (B) the “solar power system?” • ANSWER: (A) cytoskeleton • (B) chloroplasts

  19. Cell Structure and FunctionMatching P. Has enzymes)

  20. $10 Picture It • What is this in the cell picture? • ANSWER: • Golgi apparatus

  21. $20 Picture It • How could you tell the difference between ER and Golgi in a cell picture? • ANSWER: ER is connected and Golgi are not connected stacks

  22. $30 Picture It • How could you tell differences between mitochondria and chloroplasts? • ANSWER: mitochondria have wavy inner membrane and chloroplasts have green stacks

  23. $40 Picture It • Draw a red blood cell in a hypertonic solution. Draw the arrows of the flow of water. Identify the hypertonic and the hypotonic solutions.

  24. hypo

  25. $50 Picture It • How would you tell the difference in a cell diagram among: • Vacuoles • Lysosomes • Ribosomes?
