1. Reproduction
Bell ringer: Name and explain 1 thing that may increase the risk of cancer.

2. Reproduction
All organisms, like these animals, need to reproduce

3. Reproduction There are two kinds of reproduction: sexual and asexual
Sexual reproduction produces offspring that are different from the parents
Asexual reproduction produces offspring that are genetically identical to the parents

4. Asexual reproduction
In asexual reproduction, the offspring are identical to the parent. They are known as clones
Much like Boba Fett and Jango Fett from Star Wars

5. Kinds of Asexual Reproduction
One way organisms reproduce asexually is actually mitosis.
Bacteria do a similar process but we call it binary fission.

6. Kinds of Asexual Reproduction
Budding is when the parent grows a genetically identical offspring on its body, and then the offspring breaks away

7. Kinds of asexual Reproduction
Regeneration occurs when an offspring grows from a piece of the parent.

8. Kinds of asexual reproduction
Vegetative reproduction is a form of asexual reproduction in which offspring grow from a part of a parent plant.

9. Kinds of asexual reproduction
Cloning is a type of asexual reproduction performed in a laboratory that produces identical individuals from a cell or from a cluster of cells taken from a multicellular organism.
Scientists have been able to clone many animals with the chromosomes from one parent.

10. Asexual reproduction No mate necessary Saves time and energy
Advantages
Disadvantages
No mate necessary
Saves time and energy
Can produce large numbers of offspring all at once
Can result in harmful mutations
No variation (everything is identical) so if there are bad genes they are constantly passed on

11. Brain pop!

12. Bell Ringer: name an advantage or disadvantage of asexual reproduction

13. Sexual Reproduction
In sexual reproduction, a female and male sex cell come together
The female sex cells are called eggs
The male sex cells are called sperm

14. Sexual Reproduction
Fertilization is the process through which the sperm and egg join.
When the sperm joins with the egg they create something called a zygote

15. Diploid cells
Organisms that reproduce sexually form body cells (muscle, bone, etc.) and sex cells (sperm and egg)
In body cells of most organisms, similar chromosomes occur in pairs.
Diploid cells are cells that have pairs of chromosomes.
All cells in your body are diploid except for sperm and egg

16. Diploid cells
Pairs of chromosomes that have genes for the same traits arranged in the same order are called homologous chromosomes.
Because one chromosome is inherited from each parent, the chromosomes are not identical.
Different organisms have different numbers of chromosomes.

17. Diploid cells

18. Haploid cells
Some cells have only half the number of chromosomes. These are haploid cells.
In your body only the sperm and egg cells are haploid.
When two haploid sex cells meet, they form a diploid zygote.

19. Sexual reproduction
Advantages
Disadvantages
Genetic variation
Due to genetic variation, individuals have slight differences.
Genetic variation may enable organisms to be more disease-resistant, or stronger or have some other advantage over another member of the same species.
Organisms have to grow and develop until they are mature enough to produce sex cells.
Organisms must form sex cells—either eggs or sperm.
