Asexual Reproduction Anna Ward Ridge Road MS

Science Starter Please read the two articles provided. Answer the following questions on a separate sheet of paper using complete sentences. DO NOT WRITE ON THE PAPER. This is a class copy. Passage 1: What is the name of the process salamanders use to regrow their tails? In your own words, how does this happen? What form of reproduction does this represent (asexual or sexual)? How do you know? Do all bees reproduce asexually? What information in the passage leads you to this conclusion. Which passage did you find more interesting, and why? When you are done, please complete the video and question on Google Classroom.

Announcements Asexual and Sexual Reproduction Quiz on Wednesday I will return your science fair sheets with feedback tomorrow Start background research (open a Google Docs, don’t forget to cite the sources you are getting your info) Do NOT try to trade in stickers during the Warm-Up or right before transitions…INDEPENDENT WORK

Asexual Reproduction: A type of reproduction in which a single organism produces offspring that have the same genetic material Sexual Reproduction: A type of reproduction in which male and female reproductive cells combine to form offspring with genetic material from both cells Mitosis: Cell division resulting in two identical cells Meiosis: Cell division resulting in four sex cells with half the normal amount of genetic material Gametes: A sperm or egg cell that contains half the usual number of chromosomes Gene: The basic unit of heredity that consists of a segment of DNA on a chromosome Heredity: The passing of genes from parent to offspring Traits: Characteristics that inherited from parent to offspring DNA: The genetic material found in all living cells Chromosomes: The physical structure in the cell that contains the cell’s genetic material Genome: The full DNA sequence of an organism Mutation: Any change made in DNA

Asexual Reproduction…(Page 4) Asexual Reproduction is when a single organism produces offspring that have the same genetic material Some Examples: Budding (Hydra) Fragmentation (Some kinds of worms) Regeneration (Starfish) Binary Fission (Bacteria) Mitosis (Cell Division) https://www.youtube.com/watch?v=hXaswpUjK-M

Benefits of Asexual Reproduction… Asexual Reproduction has benefits: Organisms can reproduce quickly Necessary for organisms to grow and develop Allows for repair of damage to the organism Can pass on all of your genetic information Do not have to find a mate
