1.

What are the main phases of mitosis?

a)

Prophase, Anaphase, Telophase, Meiosis

b)

Interphase, Prophase, Anaphase, Telophase

c)

Prophase, Metaphase, Anaphase, Telophase, Cytokinesis

d)

Prophase, Metaphase, Cytokinesis, Interphase

2.

Describe the prophase stage of mitosis.

a)

Prophase is the final stage of mitosis where cells divide.

b)

During prophase, the DNA is replicated and the cell grows larger.

c)

Prophase is the first stage of mitosis where chromosomes condense, the nuclear envelope disintegrates, and the mitotic spindle forms.

d)

Prophase is when the chromosomes are invisible and the nuclear envelope is intact.

3.

What occurs during metaphase in mitosis?

a)

Chromosomes replicate and move to opposite poles.

b)

Chromosomes align at the metaphase plate and spindle fibers attach to their centromeres.

c)

Spindle fibers disassemble and chromosomes decondense.

d)

Nuclear envelope re-forms around the chromosomes.

4.

Explain the significance of anaphase in mitosis.

a)

Anaphase is when DNA is replicated before cell division.

b)

Anaphase is the stage where the nuclear envelope re-forms.

c)

Anaphase is significant for the synthesis of proteins in the cell.

d)

Anaphase is significant in mitosis because it ensures the accurate separation and distribution of sister chromatids to the daughter cells.

5.

What happens during telophase in mitosis?

a)

Cytoplasm divides and two new cells form

b)

Chromosomes de-condense, nuclear envelope re-forms, and nucleolus reappears.

c)

Spindle fibers disappear and cells divide

d)

Chromosomes align at the equatorial plate

6.

How does cytokinesis differ in plant and animal cells?

a)

Cytokinesis is identical in both plant and animal cells.

b)

Plant cells use a cleavage furrow, while animal cells form a cell plate.

c)

Animal cells form a cell plate, while plant cells use a cleavage furrow.

d)

Cytokinesis differs in that animal cells use a cleavage furrow, while plant cells form a cell plate.

7.

List the phases of meiosis.

a)

Prophase I, Metaphase I, Anaphase I, Telophase I, Prophase II, Metaphase II, Anaphase II, Telophase II

b)

Prophase I, Metaphase II, Anaphase II, Telophase II

c)

Prophase A, Metaphase A, Anaphase A, Telophase A

d)

Prophase I, Metaphase I, Anaphase I, Telophase II

8.

What is the role of prophase I in meiosis?

a)

Prophase I involves the formation of the nuclear envelope.

b)

Prophase I is the stage where DNA replication occurs.

c)

Prophase I is responsible for separating sister chromatids.

d)

Prophase I facilitates homologous chromosome pairing and genetic recombination.

9.

Describe the events that occur during metaphase I of meiosis.

a)

Spindle fibers disassemble and chromosomes condense.

b)

Chromosomes replicate and form tetrads.

c)

Homologous chromosomes align at the metaphase plate, spindle fibers attach to centromeres.

d)

Sister chromatids separate and move to opposite poles.

10.

What is the significance of anaphase I in meiosis?

a)

Anaphase I is when sister chromatids separate.

b)

Anaphase I occurs after fertilization in sexual reproduction.

c)

Anaphase I separates homologous chromosomes, reducing chromosome number and increasing genetic diversity.

d)

Anaphase I duplicates chromosomes for cell division.

11.

Explain the difference between telophase I and telophase II in meiosis.

a)

Telophase I involves the separation of sister chromatids, while telophase II involves the separation of homologous chromosomes.

b)

Telophase I occurs only in mitosis, while telophase II occurs in meiosis.

c)

Telophase I and telophase II are identical processes with no differences.

d)

Telophase I involves the separation of homologous chromosomes, while telophase II involves the separation of sister chromatids.

12.

What are the key differences between mitosis and meiosis?

a)

Mitosis involves two rounds of division; meiosis involves one round of division.

b)

Mitosis produces 4 identical cells; meiosis produces 2 genetically identical cells.

c)

Mitosis occurs only in gametes; meiosis occurs in somatic cells.

d)

Mitosis results in 2 identical cells; meiosis results in 4 genetically diverse cells.

15.

What is the main purpose of mitosis compared to meiosis?

a)

Mitosis is for sexual reproduction; meiosis is for growth.

b)

Mitosis occurs only in plants; meiosis occurs in animals.

c)

Mitosis produces four cells; meiosis produces two cells.

d)

Mitosis is for growth and repair; meiosis is for sexual reproduction.
