Mitosis and Meiosis Review

Mitosis and Meiosis Review

Multiple Choice

The diagram shows the stages in the cell cycle.

At what point does the cell undergo cytokinesis?

• point W

• point X

• point Y

• point Z

Multiple Choice

The diagram shows the chromosome number during mitosis.

How is mitosis important in the reproduction of organisms?

• Mitosis ensures the chromosome number of the daughter cells is identical to the parent cells, allowing unicellular organisms to reproduce identical offspring sexually.

• Mitosis ensures the chromosome number of the daughter cells is identical to the parent cells, allowing unicellular organisms to reproduce identical offspring asexually.

• Mitosis ensures the chromosome number of the daughter cells is half that of the parent cells, allowing unicellular organisms to reproduce more diverse offspring sexually.

• Mitosis ensures the chromosome number of the daughter cells is half that of the parent cells, allowing unicellular organisms to reproduce more diverse offspring asexually.

Multiple Choice

Which statement is true about mitosis?

• It is a form of asexual reproduction resulting in daughter cells that each have half the number of chromosomes as the parent cell.

• It is a form of asexual reproduction resulting in daughter cells that each have one set of chromosomes identical to the parent cell.

• It is a form of sexual reproduction resulting in daughter cells that each have half the number of chromosomes as the parent cell.

• It is a form of sexual reproduction resulting in daughter cells that each have one set of chromosomes identical to the parent cell.

Multiple Choice

The diagram shows a cell in different stages of mitosis.

Which stage represents the events taking place during anaphase of mitosis?

• stage 1

• stage 2

• stage 3

• stage 4

Multiple Choice

A teacher showed slides of different stages of mitosis to four students and asked them to describe the stage viewed under the microscope.

Which student correctly described the stage?

• student 1

• student 2

• student 3

• student 4

Multiple Choice

The diagram shows the phases of mitosis in an animal cell.

When does cytokinesis occur?

• after prophase is complete

• after telophase is complete

• during anaphase when the chromosomes are being separated

• during interphase when the DNA is being replicated

Multiple Choice

The incomplete model shows a process the cell goes through to form a new cell.

Which process is shown in the model?

• meiosis

• mitosis

• chromosome duplication

• DNA formation

Multiple Choice

The diagram shows sister chromatids that have undergone the process of crossing over.

What is the significance of crossing over?

• It increases the number of different gene combinations in the gametes.

• It decreases the number of chromosomes in the gametes.

• It increases the number of chromosomes in the gametes.

• It decreases the number of genes per chromosome in the gametes.

Multiple Choice

A cell has two pairs of homologous chromosomes. They undergo cell division, as shown.

Which statement identifies the process and explains how genetic information gets transferred to the daughter cells?

• Mitosis; the homologous chromosomes combine before duplicating and exchange information to form daughter cells.

• Meiosis; the homologous chromosomes duplicate in number twice and separate as pairs in daughter cells.

• Meiosis; the homologous chromosomes exchange segments with each other and divide twice to form daughter cells.

• Mitosis; the homologous chromosomes copy information from each other and divide twice to form daughter cells.

Multiple Choice

The gametes of human males and females have the same number of chromosomes. Which best describes what happens to the chromosomes when typical male and female gametes combine to produce offspring?

• The chromosomes become larger in size.

• The number of chromosomes reduces by half.

• The chromosomes change shape.

• The number of chromosomes doubles.

Multiple Choice

Which statement is true regarding meiosis in cells?

• In anaphase I, sister chromatids are pulled apart at the centromere.

• In prophase II, homologous chromosomes are paired up in a tetrad.

• The daughter cells do not undergo cytokinesis at the end of meiosis I.

• The products of telophase I are two haploid daughter cells.

Multiple Choice

In which activity does meiosis play a role?

• formation of an embryo

• production of sex cells

• replacement of dying cells

• growth and repair of tissues

Multiple Choice

There are two types of reproduction as shown in the diagram.

What labels should be given to letters W and X to identify each type of reproduction and for letters Y and Z to identify each method of cell division?

• W: Sexual X: Asexual

  Y: Meiosis Z: Mitosis

• W: Sexual X: Asexual

  Y: Mitosis Z: Meiosis

• W: Asexual X: Sexual

  Y: Meiosis Z: Mitosis

• W: Asexual X: Sexual

  Y: Mitosis Z: Meiosis
