Aim # 52: How do organisms reproduce?
Do Now:
1) What is cancer?
2) What is the difference between a benign and
malignant tumor?
3) What is metastasis?
4) Name three methods of treatment.

1)Daily Review of Class Notes
Aim #52: How do organisms reproduce?
1) Who thinks they can define
Reproduction?
The process by which living things produce other
living things like themselves.
The production of offspring.
2) What are Chromosomes?
Found in
Nucleus
XX
XX
Structures found in the nucleus of our cells that determine our
physical characteristics (traits). They have the genetic information
(DNA).
Chromosomes need to be passed
onto the offspring. They are the
“instructions” for the cell.

3) Types of Reproduction:
Asexual Reproduction

Genetic Information
(Chromosomes)
Characteristics of Asexual Reproduction:
1) Is the creation of a new individual from only 1 parent.
2) Genetic information of offspring is identicalto the parent.
Do the cells in our body undergo asexual
reproduction?
Yes
4) When do the cells of our body
undergo Asexual Reproduction?
Growth
Repair
Some types of Asexual Reproduction:
(Mitosis)
5) Some organisms are capable of
Regeneration
Development of lost parts or
growth of an entire new
organism from part of original
organism
Examples: Sea star and Planaria
6) Identify and define the types of Asexual
Reproduction below:
Binary Fission: The splitting of a
one-celled organism into 2 equal size
offpsring.
Example: Bacteria & Amoeba
6) Identify and define the types of
Asexual Reproduction below:
Budding: a new cell is formed from a tiny bud on the parent
cell (cytoplasm divides unequally)
Examples: Yeast (unicellular), hydra (multicellular)

7) What is Sexual Reproduction?
It involves the joining of two cells to begin the
development of a new individual.
These special cells are called: Sex Cells (Gametes)
8) What are the names of these sex cells?
Egg cell
(Female)
Sperm Cell
(Male)
9) The joining of a sperm cell with
an egg cell is called fertilization.

Offspring
A fertilized egg cell is called a Zygote
Characteristics of Sexual Reproduction:
1) Is the creation of a new individual from 2 parents.
2) Offspring are not genetically identical to the parents.
10) We get half our genetic information
from mom and half our genetic
information from dad

11) Asexual vs. Sexual Reproduction
1 Parent
Offspring are
identical
Bacteria, Amoeba,
