AIM: How does life continue?

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

FEMALE

MALE

What type of reproduction occurs here?

MALE PARTSFEMALE 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
