Sexual and Asexual Reproduction

Multiple Choice

The new cells formed at the end of cell division are called...

Parent Cells

Daughter Cells

Sister Cells

Multiple Choice

The process of forming offspring from ONE parent is called...

Sexual Reproduction

Asexual Reproduction

Unicellular Reproduction

Diploid

Diploid = full set of chromosomes
Chromosomes = smaller chunks of DNA

Diploid in Organisms You Know

Diploid in dogs = 78 chromosomes
Diploid in humans = 46 chromosomes
Diploic in chimpanzees = 48 chromosomes

Why Asexual Reproduction Doesn't Require Sex

A diploid cell creates two new diploid cells - all cells have the full DNA after division.

Multiple Choice

What are smaller chunks of DNA called?

Nucleus

Diploid

Reproduction

Chromosome

Multiple Choice

If an organism reproduces asexually and the parent cell contains 32 chromosomes, how many chromosomes will the daughter cells have?

How is Sexual Reproduction Different from Asexual Reproduction?

There are 2 divisions

There are 4 daughter cells

The daughter cells are haploid = half the DNA

Diploid vs Haploid

Diploid = full set of chromosomes
Haploid = a half set of chromosomes

Haploid in Organisms You Know

If Diploid in dogs = 78 chromosomes the haploid =
If Diploid in humans = 46 chromosomes, the haploid =
Diploic in chimpanzees = 48 chromosomes, the haploid =

Gametes

Haploid cells are called gametes.

In males, they are called sperm.

In females, they are called eggs.

Why does sexual reproduction require sex?

The daughter cells are haploid = half the DNA

Fertilization is needed to combine two haploid cells to make a new diploid cell.

Multiple Choice

Cats have 38 chromosomes in their DNA. How many chromosomes would be in the egg cell of a cat?

Multiple Choice

Which of the following best describes the result of sexual reproduction?

Two haploid cells combine to form a diploid cell after fertilization.

Two diploid cells combine to form one haploid cell after fertilization.

A haploid and diploid cell combine to form a zygote after fertilization.
