Today, we’re talking about Asexual Reproduction Please title your notes “Asexual Reproduction” on page 26 of your science notebook Fun Fact: the suffix “a” means “without”

Asexual Reproduction…Page 26 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)

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

In Sexual Reproduction… Sexual Reproduction: A type of reproduction in which male and female reproductive cells combine to form offspring with genetic material from both cells DNA from two parent organisms merges to create a new organism Uses GAMETES (sex cells) Sperm and Egg

Single Celled Organisms http://www.teachersdomain.org/resource/tdc02.sci.life.stru.singlecell/ What type of reproduction -- asexual or sexual -- do most single-celled organisms use? What must a single-celled organism do before it can reproduce? When a single-celled organism reproduces, what is the result? In what ways, if any, does a single-celled organism differ from its parent?

Sexual encounters of the Floral Kind http://www.teachersdomain.org/resource/tdc02.sci.life.stru.floral/ What type of reproduction -- asexual or sexual -- do most plants use? What nonliving force do plants rely on most often for pollination? What are some of the ways in which plants encourage or trick animals into carrying their pollen to other plants? What proportion of each parent plant's genetic material does each offspring plant have?

Asexual Reproducers http://www.teachersdomain.org/resource/tdc02.sci.life.repro.asexual/ What type of reproduction -- asexual or sexual -- do the whiptail lizards in the video use? How many parents do whiptail lizards have? How do young whiptail lizards differ from their parents, if at all? How much of their parent's genetic material do whiptail lizards have?

The Red Queen http://www.teachersdomain.org/resource/tdc02.sci.life.evo.redqueen/ What are the differences between the two species of minnows featured in the video? Which species -- the asexual or the sexual reproducers -- tends to be more heavily parasitized by the worm that causes black-spot disease? How are the sexual reproducers able to evolve defenses against parasites more quickly and more effectively than their asexual counterparts?

The Mating Game Read the Article and Answer these three questions in your science notebook on page 27 Why does sexual reproduction provide more genetic variation? Why would sexual reproduction be an advantage to a species? What would be a disadvantage of sexual reproduction?
