Cell Division MCQ Quiz: Exam!
(163).jpg "Cell Division MCQ Quiz: Exam! - Quiz")
What is cell division? Cell separation is the procedure by which a parent cell splits into two or more daughter cells. Cell division typically occurs as part of a larger cell cycle. In cell biology, mitosis is part of the cell cycle in which replicated chromosomes are separated into new nuclei. Cell division creates genetically identical cells in which the total number of chromosomes is preserved. This quiz will explain all about cell division.
- 1.
One difference between cytokinesis in plant cells and in animal cells is that plant cells have
- A.
A cell plate.
- B.
Chromatin.
- C.
Centrioles.
- D.
Centromeres
Correct Answer
A. A cell plate.Explanation
Plant cells have cell walls which prevent the cell membrane from "pinching in" so they build a cell plate to divide the cytoplasm.Rate this question:

During which phase of mitosis do the chromosomes line up along the equator (middle) of the dividing cell?
- A.
Metaphase
- B.
Telophase
- C.
Anaphase
- D.
Prophase
Correct Answer
A. MetapHaseExplanation

- 3.
Crossing-over does not occur in mitosis, unlike meiosis. Which of the following is the likely reason?
- A.
Chromatids are not involved in mitosis.
- B.
A cell undergoing mitosis does not have homologous chromosomes.
- C.
There is no prophase during mitosis.
- D.
Homologous chromosomes do not pair up during mitosis.
Correct Answer
D. Homologous chromosomes do not pair up during mitosis.Explanation
Homologous chromosomes pair up during meiosis in order to exchange genes and ensure that each of the 4 gametes produced have 1 copy of each gene. Mitosis produces genetically identical cells so all of the chromosomes line up independently on the spindle.Rate this question:

DNA replicates during cytokinesis.
Correct Answer
B. InterpHase consists of the G1, S, and, G2 pHases.Explanation
Interphase is the longest stage of the cell cycle consisting of G1 (growth), S (DNA replication) and G2 (preparation for mitosis).Rate this question:

- D.
Interphase is usually the longest phase.
Correct Answer

- B.
Between Prophase II and Anaphase II
- C.
During Interphase
- D.
Crossing over only occurs during Mitosis
Correct Answer
A. Between PropHase I and AnapHase IExplanation
Crossing over occurs when Homologous Chromosomes pair up during Prophase I and separate during Anaphase I.Rate this question:

- A.
Anaphase
- B.
Metaphase
- C.
Prophase
- D.
Telophase
Correct Answer
A. AnapHaseExplanation
Anaphase pulls apart sister chromatids.Rate this question:
-
- 10.
At what point are the cells in Meiosis first considered haploid?
- A.
Prophase I
- B.
Prophase II
- C.
Telophase II
- D.
Haploid cells are NOT present throughout in meiosis.
Correct Answer
B. PropHase IIExplanation
At the end of Telophase I (and through all of Meiosis II), the cells are haploid.Rate this question:
-

Unlike mitosis, meiosis results in the formation of
- A.
4 diploid cells.
- B.
2 diploid cells.
- C.
4 haploid cells.
- D.

Which of the following is a major difference between the production of gametes in males and females?
- A.
