1. Aim: How do organisms reproduce?

2. The diagrams below illustrate types of asexual reproduction.
DO NOW :
The diagrams below illustrate types of asexual reproduction.
Which statement correctly describes the offspring?
They vary genetically from the parent
(2) They are produced by the union of gametes
(3) They obtain nourishment from a placenta
(4) They result without the union of gametes

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

4. What are Chromosomes? cell
Found in Nucleus XX
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.
The cell wouldn’t be able to perform its
functions without them.

Genetic Information
(Chromosomes)
*Is the creation of a new individual from only parent. 1
*Genetic information of offspring is to the parent
identical

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

7. What is Regeneration? The ability of organisms
to grow back limbs if they
are cut off.

8. Types of Asexual Reproduction:
Fission: The splitting of a one-celled organism into 2 equal halves.

9. Types of Asexual Reproduction:
Budding: a new cell is formed from a tiny bud on the parent cell.

10. 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)

11. Identify the gametes below:
Sperm Cell (Male)
Egg cell (Female)

12. *The joining of a sperm cell with an egg cell is called fertilization.
*A fertilized egg cell
is called a Zygote

Characteristics of Sexual Reproduction:
*It’s the creation of a new individual from parents. 2
*Offspring are not genetically to the parents.
