MITOSIS AND MEIOSIS QUIZ

What moves the chromatids during mitosis?

Spindle fibers

During what phase does cytokinesis begin?

Telophase

During which stage of mitosis does cytokinesis usually occur in animals?

Telophase

One division

Mitosis

Two daughter cells produced

Mitosis

Involves duplication of chromosomes

Mitosis and Meiosis

What is mitosis and meiosis and why are they important?

Mitosis and meiosis both involve cells dividing to make new cells. This makes them both vital processes for the existence of living things that reproduce sexually. Meiosis makes the cells needed for sexual reproduction to occur, and mitosis replicates non-sex cells needed for growth and development.

How many daughter cells are created from mitosis and cytokinesis?

Two

What structure holds the individual chromatids together?

Centromere

What is the correct order of the 4 stages of mitosis?

1. Prophase 2. Metaphase 3. Anaphase 4. Telophase

Name three things that mitosis is used for.

1. Repair (of a wound) in multicellular organisms 2. Asexual reproduction in unicellular organisms 3. Development (e.g., baby in mother's womb)

If a dog cell has 72 chromosomes, how many daughter cells will be created during a single cell cycle? _____ .....Each of these daughter cells will have how many chromosomes? ___72_______

2, 72

In the cell pictured above, how many chromosomes are present during prophase?

4

If a human cell has 46 chromosomes, how many chromosomes will be in each daughter cell?

46

What anchors the spindle?

Centrioles

Associated with sexual reproduction

Meiosis

Chromosome number is halved

Meiosis

Crossing over between homologous chromosomes may occur

Meiosis

Daughter cells are not identical to parent cell

Meiosis

Four daughter cells produced

Meiosis

Synapsis occurs in prophase

Meiosis

Meiosis

_________ only occur(s) in the gonads to produce gametes.

Meiosis

Associated with growth and asexual reproduction

Mitosis

Chromosome number is maintained

Mitosis

Daughter cells are identical to parent cell

Mitosis

Mitosis

During which stage of mitosis do the centromeres split?

Anaphase
