Mitosis vs Meiosis

Mitosis vs Meiosis

Lesson Objective: Students will be able to compare and contrast Mitosis vs Meiosis as well as be able to identify the stages of Meiosis. Feel free to take notes on the following information.

Mitosis

Mitosis is used for growth and repair in cells. This is a form of asexual reproduction. Mitosis creates somatic (body) cells that are classified as diploid. Diploid means that there is 2 complete sets of chromosomes. 1 set from the mother and 1 set from the father.

Multiple Select

What is mitosis used for?(check all that apply)

• Growth

• Repair

• Producing sex cells

• Producing Sperm

• Producing Eggs

Meiosis

Meiosis is used to produce sex cells: sperm and ova(eggs). Each sex cell created has half the amount of chromosomes as the parent cell. Since they have half the amount of chromosomes and only 1 set of chromosomes we classify them as haploid.

Multiple Select

What does Meiosis produce? (check all that apply)

• Identical cells

• sperm cells

• egg cells

• Somatic Cells

Mitosis Characteristics

• Makes Somatic Cells aka Body Cells

• Has 1 division

• Creates 2 genetically identical daughter cells

• Asexual Reproduction

• Creates cells that are Diploid aka 2N: Diploid = 2 complete sets of chromosomes - 1 from each parent

Mitosis Stages

There is 4 stages in Mitosis: Prophase, Metaphase, Anaphase, and Telophase.

Multiple Choice

What acronym do we use to remember the order of Mitosis?

• AMPT

• TMAP

• PMAT

• TAMP

Prophase

• The chromatin starts to condense into chromosomes.

• The Nuclear membrane starts to dissolve/disappear.

• The spindle fibers start to form.

Multiple Choice

Which is not a characteristic of Prophase?

• Nuclear membrane starts to dissolve

• Chromatin condenses into chromosomes

• Spindle fibers start to appear

• Sister chromatids line up in the middle of the cell

Metaphase

• Chromosomes line up on the metaphase plate. (The middle)

• Spindle fibers attached to the centromere of each set of chromosomes.

Multiple Choice

Where do the spindle fibers attach to on chromosomes?

• Top

• Bottom

• Centromere

Anaphase

• Spindle fibers pull sister chromatids apart to opposite sides of the cell.

Telophase

• Nuclear membrane reforms around both new sets of chromosomes.

• Spindle fibers disappear.

Multiple Choice

Which phase of the cell cycle always happens before Mitosis?

• Interphase

• Meiosis

• Mitochondria

• Phosphorylation

Meiosis Characteristics

• Makes Gametes aka Sex Cells

• There are 2 types of gametes: Sperm cells for males, and Ova(Eggs) for females

• Has 2 divisions that take place: Meiosis I and Meiosis II

• Creates 4 genetically unique daughter cells: 4 Sperm for males and 1 egg and 3 polar bodies for females.

• Sexual Reproduction

• Creates Haploid (N) cells which have half the amount of chromosomes as the parent cell

Multiple Choice

• Unique

Multiple Choice

Is Meiosis sexual or asexual reproduction?

• Sexual

• Asexual

Multiple Choice

Meiosis creates haploid or diploid cells?

• Haploid

• Diploid

Meiosis Phases

• Meiosis has 2 divisions that take place: Meiosis I and Meiosis II

• Both divisions have Prophase, Metaphase, Anaphase, and Telophase.

Prophase I

• Nuclear membrane starts to dissolve

• Chromosomes condense

• Homologous chromosomes pair up

• Crossing over occurs between homologous chromosomes

• Spindle fibers start to appear

Multiple Choice

When does crossing over occur?

• Prophase I

• Prophase II

• Metaphase I

• Anaphase I

Metaphase I

• The homologous pairs randomly align at the middle of the cell (Random Assortment) by spindle fibers.

Anaphase I

• The homologous chromosomes are pulled to opposite sides of the cell.

Telophase I

• Nuclear membrane reforms around new sets of chromosomes.

• Spindle fibers disassemble

Prophase II

• Nuclear membrane disassembles

• Spindle fibers start to form

Metaphase II

• Spindle fibers assemble the chromosomes at the metaphase plate(middle)

Anaphase II

• Spindle fibers pull sister chromatids apart to opposite sides of the cell.

Telophase II

• Nuclear membrane starts to reform around new sets of chromosomes

• Spindle fibers disassemble
