HW:
Daily Review of Class Notes
Do Now:
What is cancer?
What is the difference between a benign and malignant tumor?
What is metastasis?
Name three methods of treatment.

2. Aim #52: How do organisms reproduce?

3. 1) Who thinks they can define Reproduction?
The process by which living things produce other
living things like themselves.
The production of offspring.

4. 2) What are Chromosomes? Found in Nucleus cellXX
cell
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.

5. 3) Types of Reproduction: Asexual Reproduction

Genetic Information
(Chromosomes)
Characteristics of Asexual Reproduction:
1) Is the creation of a new individual from only parent. 1
2) Genetic information of offspring is to the parent.
identical

6. Do the cells in our body undergo asexual reproduction?
Yes
4) When do the cells of our body undergo Asexual Reproduction?
Repair
Growth

7. Some types of Asexual Reproduction: (Mitosis)

8. 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

9. 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

10. 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)

12. 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)

13. 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.

14. Sexual Reproduction + Offspring EggXX XX XX +
Offspring
Egg
Sperm
A fertilized egg cell is called a Zygote
Characteristics of Sexual Reproduction: 2
1) Is the creation of a new individual from parents.
2) Offspring are not genetically to the parents.
identical

15. 10) We get half our genetic information from mom and half our genetic information from dad23 23
Females:
Egg cells
Males:
Sperm cells
