AIM: How does life continue?
•Define the types of reproduction•Define the term offspring
reproduction,
asexual reproduction,
sexual reproduction,
offspring, Fission, budding
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
