2 AIM: How does life continue? Define the types of reproduction Define the term offspring

3 reproduction, asexual reproduction, sexual reproduction, offspring, Fission, budding AIM: How does life continue?

5 Why is reproduction important? Keeps the species going produces more of the species insures that life continues

6 What is an offspring? something a living thing produces to ensure the survival of its species baby of a parent A seed

10 What type of reproduction occurs here? MALE PARTS FEMALE PARTS

12 Asexual Reproduction involves the reproduction of one-celled organisms: Bacteria Yeasts Amoeba

19 Two Cells produced of “equal” size, both much smaller then the original. What happens next?

20 Eventually both cells grow into a full size original. And the reproduction process begins all over again.

23 A bud, or node, begins to form

24 The bud begins to separate from the rest of the cell.

25 The bud is now a separate cell, and a fraction of the size of the original parent

26 Gradually the new cell grows and grows until …

27 The offspring is the same size as the original

34 Reproduction: Process by which living things produce new organisms like themselves

35 Offspring: New organisms produced by a living thing

36 Sexual Reproduction: Reproduction needing two parents. Whose offspring has a genetic code which is a mixture of both parents

37 asexual Reproduction: Reproduction needing one parents. Whose offspring has a genetic code which is identical to the parent.

38 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

39 Differentiate the two types of reproduction Define reproduction Define the term offspring

40 Class Activity: Worksheets: 2-5 What are the ramifications of cloning ? AIM: How does life continue?
