Cell Theory, Organelles, Cell Cycle and Cancer

Delve into the fundamentals of cell theory, organelles, cell cycle, and cancer. Learn about the smallest living unit and how specialized structures within cells function together. Explore the classification of cells, cell membranes, stem cells, and the phases of mitosis. Differentiate between malignant and benign tumors and grasp the concept of uncontrolled cell growth in cancer.

Presentation Transcript

  1. Cell Theory, Organelles, Cell Cycle and Cancer

  2. All living things are made up of the smallest living unit called __________.

  3. Cells

  4. Specialized structures within the cell that work together to help the cell function are called _______________.

  5. Organelles

  6. Cells that have NO nucleus and that are primarily unicellular are classified as _______________.

  7. Outside of cell Carbohydrate chains Proteins Cell membrane Protein channel Inside of cell (cytoplasm) Lipid bilayer What is the circled molecule that makes up the bilayer of our cell membranes?

  8. Phospholipid

  9. List the THREE main phases of the cell cycle.

  10. Interphase, Mitosis, Cytokinesis

  11. Differentiate between embryonic and adult stem cells.2 points

  12. Embryonic: From embryo; have never differentiated.Adult: From bone marrow; partially differentiated.

  13. What happens during the Sphase of Interphase?

  14. Chromosomes (DNA) replicates/duplicates.

  15. Draw a chromosome and label:ChromatidCentromereTelomere3 points

  16. See whiteboard.

  17. WHAT PHASE IS SEEN HERE?

  18. TELOPHASE

  19. Chromatin condenses into chromosomes; nuclear membrane breaks down

  20. PROPHASE

  21. WHAT PHASE IS SEEN HERE?

  22. METAPHASE

  23. Give 1 of the 3 parts of the cell theory?

  24. 1. All living things are made of cells2. Cells give basic structure and function to organisms3. Cell come from pre-existing cells

  25. Sister chromatids separate and move to opposite poles.

  26. ANAPHASE

  27. WHAT PHASE IS SEEN HERE?

  28. PROPHASE

  29. Chromosomes line up in the middle; spindle fibers connect to centromere.

  30. METAPHASE

  31. WHAT PHASE IS SEEN HERE?

  32. ANAPHASE

  33. Chromosomes gather at opposite ends of the cell and two new nuclear membranes form.

  34. TELOPHASE

  35. Pre-programmed cell death.

  36. Apoptosis

  37. What is cancer?Second to last question…

  38. Uncontrolled cell growth.

  39. Differentiate between malignant and benign tumors.2 points

  40. Malignant: Can break off and spread.Benign: Remain clustered and typically harmless.
