3.

What is the purpose of mitosis?

a)

To produce genetically diverse offspring

b)

To produce four daughter cells with half the number of chromosomes as the parent cell

c)

To produce two identical daughter cells with the same number of chromosomes as the parent cell.

d)

To repair damaged DNA in the cell

4.

How many daughter cells are produced in mitosis?

a)

3

b)

5

c)

4

d)

2

5.

What is the end result of meiosis?

a)

Four daughter cells with half the number of chromosomes

b)

Two daughter cells with the same number of chromosomes

c)

One daughter cell with double the number of chromosomes

d)

Three daughter cells with half the number of chromosomes

6.

Which type of cell division results in genetically identical daughter cells?

a)

Binary fission

b)

Budding

c)

Meiosis

d)

Mitosis

7.

What is the significance of cytokinesis in the cell cycle?

a)

Cytokinesis leads to the formation of new organelles in the cell

b)

Cytokinesis occurs before DNA replication in the cell cycle

c)

Cytokinesis is essential for the completion of the cell cycle and the generation of two genetically identical daughter cells.

d)

Cytokinesis is only relevant in prokaryotic cells

8.

What are the stages of mitosis in order?

a)

prophase, metaphase, anaphase, telophase, prometaphase

b)

telophase, prophase, metaphase, anaphase, prometaphase

c)

prophase, prometaphase, metaphase, anaphase, telophase

d)

interphase, metaphase, telophase, anaphase, prophase

9.

What is the difference between mitosis and meiosis?

a)

Mitosis produces genetically identical daughter cells, while meiosis produces genetically diverse daughter cells

b)

Mitosis occurs in somatic cells, while meiosis occurs in gametes

c)

The difference is in the timing of cell division

d)

The main difference between mitosis and meiosis is the number of daughter cells produced and the number of chromosomes in each daughter cell.

10.

What is the role of centrioles in cell division?

a)

Regulate gene expression

b)

Organize spindle fibers for chromosome separation

c)

Help in cell membrane formation

d)

Store excess nutrients

11.

What happens during the S phase of interphase?

a)

Protein synthesis

b)

Cell division

c)

Chromosome condensation

d)

DNA replication

12.

How does cytokinesis differ in plant and animal cells?

a)

Plant cells form a cleavage furrow during cytokinesis, while animal cells form a cell plate

b)

In both plant and animal cells, cytokinesis involves the formation of a cell plate

c)

In plant cells, cytokinesis involves the formation of a cell plate, while in animal cells, a cleavage furrow forms.

d)

Cytokinesis in plant cells occurs through the process of budding, unlike animal cells

13.

What is the importance of the G1 phase in interphase?

a)

In G1 phase, cells do not prepare for DNA replication.

b)

The G1 phase is important for cell growth, normal functions, and preparation for DNA replication.

c)

G1 phase is irrelevant to cell cycle progression.

d)

The G1 phase is responsible for protein synthesis only.

14.

What is the purpose of crossing over in meiosis?

a)

To speed up the process of meiosis

b)

To increase genetic diversity

c)

To prevent the formation of gametes

d)

To decrease genetic diversity

15.

What is the significance of telophase in mitosis?

a)

Telophase is responsible for DNA replication

b)

Telophase occurs before prophase in mitosis

c)

Telophase is significant in mitosis as it marks the completion of nuclear division and the formation of two separate nuclei.

d)

Telophase is when the cell prepares for division
