AIM: How does life continue? •Define the types of reproduction •Define the term offspring AIM: How does life continue? reproduction, asexual reproduction, sexual reproduction, offspring, Fission, budding Why is reproduction important? • Keeps the species going • produces more of the species • insures that life continues What is an offspring? • something a living thing produces to ensure the survival of its species • baby of a parent • A seed MALE FEMALE What type of reproduction occurs here? MALE PARTS FEMALE PARTS Asexual Reproduction involves the reproduction of one-celled organisms: •Bacteria •Yeasts •Amoeba Two Cells produced of “equal” size, both much smaller then the original. What happens next? Eventually both cells grow into a full size original. And the reproduction process begins all over again. A bud, or node, begins to form The bud begins to separate from the rest of the cell. The bud is now a separate cell, and a fraction of the size of the original parent Gradually the new cell grows and grows until … The offspring is the same size as the original Reproduction: Process by which living things produce new organisms like themselves Offspring: New organisms produced by a living thing Sexual Reproduction: Reproduction needing two parents. Whose offspring has a genetic code which is a mixture of both parents asexual Reproduction: Reproduction needing one parents. Whose offspring has a genetic code which is identical to the parent. Reproduction SEXUAL • 2 parents • 2 sets of DNA • offspring not identical to parents • • • • • ASEXUAL 1 parent 1 set of DNA offspring exactly identical to the parent fission or budding yeast, bacteria •Differentiate the two types of reproduction •Define reproduction •Define the term offspring AIM: How does life continue?
