  1. Asexual vs. Sexual Reproduction What’s the difference in how organisms reproduce?

  2. Reproduction of living organisms takes place in one of two ways Asexual Sexual

  3. In asexual reproduction, one individual produces offspring that are genetically identical to itself. Budding is a one method of this reproduction. In this method, the offspring grows out of the body of the parent. The Hydra is an example of this. Mitosis is how the cells divide.

  5. MITOSIS Nucleus DNA Same DNA SameDNA The original cell’s nucleus splits into 2 parts and the DNA is copied into both parts

  6. What is the process of Mitosis?

  7. Some Organisms That Reproduce By Mitosis Amoeba Ferns Green Algae Yeast Sea Anemone Hydra Sea Star

  8. Mitosis is used in Asexual reproduction As a result, all organisms that are reproduced this way look alike!!!!!

  9. How many times does the cell split in Mitosis???

  10. In sexual reproduction, two individuals produce offspring that have genetic characteristics from both parents. Sexual reproduction introduces new gene combinations in a population.

  12. MEIOSIS (this represents either the egg or sperm cell) Nucleus Chromosomes46 New cell New cell Same 46 chromosomes Same 46 chromosomes ½ chromosomes 23 ½ chromosomes 23 ½ chromosomes 23 ½ chromosomes 23

  13. Every human organism is formed sexually and has 46 chromosomes. When a sperm cell and egg cell join together, they bring 23 chromosomes each and that gives the final cell (baby) the 46 chromosomes it needs. The sperm and egg carry the genetic information of each parent and that is why babies can look different. There might be 4 different combinations for each cell.

  14. What is the process of Meiosis?

  15. Some Organisms That Reproduce By Meiosis

  16. Meiosis is used in Sexual reproduction As a result, almost all organisms that are reproduced this way look different in some ways from other organisms of the same kind.

  17. Why is there more variation in offspring that result from sexual reproduction than asexual reproduction?
