1. Hot Seat Cell Structure and Function

2. What are two differences between a prokaryotic cell and a eukaryotic cell? Eukaryotic cells have a nucleus and membrane bound organelles, while prokaryotic cells do not

3. Give an example of a prokaryotic organism. Bacteria

4. Give two examples of eukaryotic organisms Plants, Animals, Protists, or Fungi

5. Describe the function and important structures of a neuron Use neurotransmitters to send and receive signals.

6. Describe the function and important structures of an intestinal cell. Use villi and microvilli to absorb nutrients. Villi and microvilli are small fingerlike projections that increase surface area

7. Describe the function and important structures of a macrophage. Engulfs microbes and uses lysosomes to digest the microbe into pieces. Alerts the immune system

8. Describe the function and important structures of a muscle cell. Uses lots of mitochondria to cause contractions for movement.

9. Describe the function and important structures of a sperm cell. Swims to the egg. Uses lots of mitochondria to power its flagellum.

10. Which organelle is responsible for digesting waste? Lysosome

11. Is this cell prokaryotic or eukaryotic? How Can you tell? Prokaryotic because the DNA is not enclosed in a nucleus.

12. Which cell structure is a tough, outer wall that provides support and protection? Cell Wall

13. Name 3 structures found in all cells. Cell Membrane Cytoplasm Ribosomes DNA Cytoskeleton

14. Which cell organelle is the location of photosynthesis? Chloroplast

15. Which cell organelle contains genetic material (DNA) Nucleus

16. What type of medicine is used to treat bacterial infections? antibiotics

17. Which cell structure controls what enters and leaves the cell? Cell Membrane

18. What is the semifluid material that surrounds organelles and is the site of many cellular reactions? Cytoplasm

19. Which cell in your body is responsible for releasing insulin to control blood sugar? Pancreatic

20. Which cell structure is the location of protein synthesis? Ribosome

21. What cell is shown above? Neuron (Nerve Cell)

22. A storage compartment that helps maintain homeostasis. Vacuole

23. Is this a prokaryotic or eukaryotic cell? How can you tell? Eukaryotic because a nucleus is present.

24. Which cell organelle is a membrane that produces proteins and lipids for export from the cell? Endoplasmic Reticulum

25. What type of cell is shown? Intestinal Cell

26. The fingerlike projections are called microvilli. Why are they important? They increase the surface area of the cell.

27. Name 3 structural differences between plant and animal cells Plant cells have a cell wall and chloroplasts, animal cells do not. Plant cells have a large central vacuole, animal cells have many small vacuoles. Animal cells have lysosomes, plant cells do not

28. Why is DNA important for cells? DNA is the code for making proteins

29. What is the function of this cell? Swim to the egg

30. What structure(s) help this cell function? microvilli

31. What structures help this cell function? Flagellum to swim Mitochondria for energy

32. Muscle cells in athletes often have more mitochondria than cells in nonathletes. Based on this observation, it can be inferred that the muscle cells in athletes A. Have a smaller demand for cell proteins than the muscle cells of nonathletes B. Reproduce less frequently than the muscle cells of nonathletes C. Have nuclei containing more DNA than nuclei in the muscle cells of nonathletes D. Have a greater demand for energy than the muscle cells of nonathletes
