Inside the Cell Video Worksheet
What are eukaryotic cells? (2 characteristics)
1. cells have nucleus
2. cells have organelles
3. Give an example of a eukaryotic cell. plant cell or animal cell
4. Every living thing on earth is composed of cells.
5. The ability to allow certain things to pass through is semi-permeability .
6. The gatekeeper of the cell is the cell membrane.
7. The “big man” or boss of the cell is the nucleus.
8. The cytoskeleton looks like long, thin tubes.
The jobs of the cytoskeleton are:
9. support
10. shape
11. strength
12. The cytoskeleton is made of protein.
13. Quick Quiz #1 Answer: ___________________________
The 3 jobs of the endoplasmic reticulum (ER) are:
14. synthesizes macromolecules
15. separates molecules
16. transports proteins
17. The organelle associated with the ER that synthesizes proteins is the ribosome.
The 2 types of ER are:
18. rough
19. smooth
20. Smooth ER synthesizes lipids.
21. Which organelle consists of flattened sacs (slightly curved)? Golgi apparatus
The organelle in #21 does 3 things to proteins which are:
22. modify
23. sort
24. package
25. Vesicles pinch off from the top of Golgi apparatus.
26. Quick Quiz Answer #2: ________________________________
27. What is the main job of the lysosome? digest worn-out organelles, debris, etc.
What would happen if the lysosome burst? Why?
28. digestive enzymes would be released and would destroy the cell.
29. Quick Quiz Answer #3: __________________________________________
30. The power house (energy producer) of the cell is mitochondria.
31. A unique characteristic of the organelle is that it can self-replicate because it has
its own DNA.
The centriole plays important roles in:
32. organizing cytoskeleton
33. cell division
34. Quick Quiz Answer #4: _______________________________
35. The control center of the cell is nucleus.
36. Chromatin is mass of DNA and protein.
37. Chromosomes are tightly coiled chromatin.
38. Mitosis is cell division.
The 4 steps of cell division are:
39. prophase
40. metaphase
41. anaphase
42. telophase
