Presentation Transcript

  1. Pick up STEPS 2-4New Topic in ISN No. 20 Asexual/Sexual Reproduction Content Obj: You will demonstrate knowledge of Asexual and Sexual reproduction by reading Like Father Like Mother and answering the questions that follow. Language Obj: You will write about Asexual and Sexual reproduction an create a Venn Diagram using the key words given to you. Reading Science Passage Taking notes Junk Box War Lab Reports due tomorrow Homework Due Friday

  2. Reproduction What is REPRODUCTION? Creation of a new individual or individuals from previously existing individuals.

  3. 2 Types of Reproduction Asexual Sexual

  4. Asexual Reproduction Only one organism is needed to reproduce. Offspring is identical to parent (100%)

  5. Paramecium Reproduces ASEXUALLY. Study the picture and describe what appears to be happening. Asexual Reproduction Binary Fission Splitting of a parent cell into two approximately equal parts.

  6. Hydra Reproduces ASEXUALLY. Study the picture and describe what appears to be happening. Asexual Reproduction BUDDING Offspring grows out of the body of the parent.

  7. Asexual Reproduction Regeneration Body of the parent breaks into distinct pieces, each of which can produce an offspring. Planarians Reproduces ASEXUALLY. Study the picture and describe what appears to be happening.

  8. Another Example of Fragmentation http://www.brainpop.com/science/cellularlifeandgenetics/asexualreproduction/

  9. Sexual Reproduction • Two organism are necessary for reproduction (Mom and Dad) • Male sex cell (sperm) and female sex cell (egg) unite to make a zygote.

  10. Sexual Reproduction • Offspring contains traits from both parents (similar to parents but not identical) • They receive 50 percent of the genes from mom and 50 percent from dad.

  11. Pick up Homework if you were absent yesterday!! • Content Obj: We will evaluate your understanding of Asexual and Sexual reproduction by creating a Venn diagram using a word bank. • Language Obj: You will demonstrate comprehension of topics taught by writing the answer to the questions on your review sheet. • Complete a Venn Diagram by correctly placing the Key words in the corresponding circle. • Work on Review for Test next Tuesday • Homework Due Friday! • Turn in Junk Box Wars Lab Report.
