Presentation Transcript

  1. Aim: How can we describe different methods of asexual reproduction? Do Now: • Draw a Venn diagram comparing & contrasting sexual & asexual reproduction

  2. HW Review • Take out your HW on binary fission and budding. • Correct your mistakes as we go along.

  3. Summarize in your notes • How is binary fission similar to budding? • How is binary fission in a paramecium different from budding in yeast?

  4. Prior Knowledge Questions • What is yeast? • What is it used for? • Discuss the life functions of yeast in baking & brewing.

  5. Binary Fission

  6. Binary Fission

  7. Budding

  8. Budding

  9. Active Reading • Begin work on the sheets being passed out.

  10. Summary • Name 3 methods of asexual reproduction. Give an example of each.

  11. Aim: How do organisms reproduce with regeneration? Do Now: • 1. Draw a Venn Diagram of BUDDING and BINARY FISSION.

  12. Summarize in your notes • Regenerationcan be used for reproduction and for cell repair. Explain using an example.

  13. Regeneration

  14. Regeneration

  15. Animation • Regeneration Animation

  16. Class Work & HW • Begin work on your regeneration HW.

  17. Aim: How do plants reproduce using vegetative propagation? Do Now • 1. Draw a picture of yeast budding. Label the parent cell and the bud. • 2. Identify 2 examples of organisms that can regenerate body parts and the parts they can regenerate.

  18. Budding

  19. Regeneration

  20. HW Review • Check your homework with a neighbor. (5 minutes) • If you are still unsure, ask your teachers.

  21. An orange with no seeds!?

  22. Vegetative Propagation • When stems, roots or leaves give rise to a new plant

  23. Video Clip • Watch the explanation of vegetative propagation. • 1) Is this asexual reproduction or sexual reproduction? Why? • 2) What part of the plant would be needed for sexual reproduction?

  24. Vegetative Propagation

  25. Advantages Disadvantages Vegetative Propagation

  26. Sexual vs. Asexual Reproduction in Plants

  27. Review Sheet • Begin work on your review sheets.

  28. Aim: How does mitosis create more cells? Do Now: Quiz • 1. What would be one advantage of asexual reproduction? Explain. • 2. Explain vegetative propagation. Give an example.

  29. Mitosis: The process of a cell dividing into two identical daughter cells. 

  30. Replication

  31. Video Clips and Animations • Mitosis Animation • Mitosis vs. Meiosis Animation • Cell Division

  32. Aim: How does mitosis work? • Do Now: Quiz • Complete the quiz. • Use words from the word bank to help you. • When you are finished, bring your quiz to the front.

  33. Motivation: Polyploidy

  34. Mitosis: The process of a cell dividing into two identical daughter cells. 

  35. Video Clips and Animations • Mitosis Animation • Mitosis vs. Meiosis Animation • Cell Division

  36. Class Work • Cut out and rearrange the steps of mitosis. • Check with your teacher to make sure you have the correct order.
