Cell Cycle Questions and Answers
- 1.
Process by which a cell divides into two new daughter cells.
- A.
Cell cycle
- B.
Cell division
- C.
Interohase
- D.
Telophase
Correct Answer
B. Cell divisionExplanation
Cell division is the correct answer because it refers to the process by which a cell divides into two new daughter cells. During cell division, the genetic material is replicated and distributed equally between the two daughter cells, ensuring that each cell receives a complete set of chromosomes. This process is essential for growth, development, and the replacement of damaged or old cells in the body.Rate this question:

Body cells that divide during mitosis.
Correct Answer
somatic cellsExplanation
Somatic cells are body cells that undergo division through the process of mitosis. Mitosis is a type of cell division that occurs in somatic cells to produce two identical daughter cells with the same number of chromosomes as the parent cell. This process is responsible for growth, repair, and maintenance of the body. Therefore, somatic cells are the correct answer as they are the specific type of cells that divide through mitosis.Rate this question:
- 3.
Sex cells divided by meiosis.
Correct Answer
gametesExplanation
Gametes are sex cells that are produced through the process of meiosis. Meiosis is a type of cell division that occurs in the reproductive organs, such as the ovaries and testes, and it results in the formation of gametes. Gametes are specialized cells that contain half the number of chromosomes compared to other body cells. They are responsible for sexual reproduction and when they fuse during fertilization, they restore the full number of chromosomes in the resulting offspring. Therefore, the given answer "gametes" accurately describes the sex cells that are divided by meiosis.Rate this question:
- 4.
Set of copied chromosomes.
Correct Answer
sister chromatidsExplanation
Sister chromatids are an identical pair of chromosomes that are formed during DNA replication. They are held together by a structure called the centromere. When a cell is preparing to divide, the sister chromatids separate and each one becomes an individual chromosome. Therefore, a set of sister chromatids refers to a group of identical chromosomes that have been copied during DNA replication.Rate this question:
- 5.
Point of attachment to the mitotic spindle.
Correct Answer
centromereExplanation
The centromere is the point of attachment to the mitotic spindle. During cell division, the mitotic spindle attaches to the centromere region of the chromosome, allowing for the proper separation of the duplicated chromosomes into two daughter cells. The centromere contains specialized DNA sequences and proteins that help ensure accurate chromosome segregation. Without a functional centromere, the chromosomes would not be able to properly align and separate, leading to errors in cell division and potential genetic abnormalities.Rate this question:
- 6.
Series of stages of cell division.
- A.
Cell division
- B.
Metaphase
- C.
Cell cycle
- D.
Prophase
Correct Answer
C. Cell cycleExplanation
The correct answer is "cell cycle". The cell cycle refers to the series of stages that a cell goes through as it divides and reproduces. This includes phases such as prophase and metaphase, which are specific stages within the cell cycle. Therefore, "cell cycle" is the most appropriate answer as it encompasses the entire process of cell division.Rate this question:

- 7.
Longest of cell cycle.
- A.
Prophase
- B.
Metaphase
- C.
Interphase
- D.
G2 phase
Correct Answer
C. InterpHaseExplanation
Interphase is the longest phase of the cell cycle. It is the period between cell divisions where the cell grows and carries out its normal functions. During interphase, the cell undergoes DNA replication to prepare for cell division. This phase is crucial for cell growth and maintaining cellular functions. Prophase, metaphase, and G2 phase are all stages within the cell cycle, but they are shorter in duration compared to interphase.Rate this question:
-
- 8.
Chromosomes line up on the metaphase plate; chromosomes are attached to the spindle fibers at centromeres.
Correct Answer
metaphaseExplanation
During metaphase, the chromosomes align themselves along the metaphase plate, which is an imaginary plane located at the center of the cell. This alignment is crucial for the equal distribution of genetic material during cell division. The chromosomes are attached to the spindle fibers at specific regions called centromeres. This attachment ensures that the chromosomes can be pulled apart and separated into two daughter cells during the subsequent phase of cell division. Therefore, the correct answer is metaphase.Rate this question:
- 9.
shortest of interphase; organelles and needed molecules are produced, the cell grows.
Correct Answer
G2 phaseExplanation
During the G2 phase of interphase, the cell continues to grow and prepare for cell division. This phase follows the S phase, where DNA replication occurs. In the G2 phase, the cell synthesizes proteins and organelles required for cell division. The cell also checks for any DNA replication errors and repairs them if necessary. Once the G2 phase is complete, the cell is ready to enter the mitotic phase and divide into two daughter cells.Rate this question:
- 10.
A minute cylindrical organelle near the nucleus in animal cells, occurring in pairs, and involved in the development of spindle fibers in cell division.
Correct Answer
CentriolesExplanation
Centrioles are small cylindrical organelles found near the nucleus in animal cells. They occur in pairs and play a crucial role in cell division. Centrioles are involved in the formation of spindle fibers, which are essential for the separation of chromosomes during cell division. These organelles are responsible for organizing and directing the movement of chromosomes, ensuring the accurate distribution of genetic material to daughter cells.Rate this question:
- 11.
“cytoplasm division”; 2 cells appear; each cell has its own nucleus with identical chromosomes; different in plants and animals.
Correct Answer
CytokinesisExplanation
Cytokinesis is the process of cytoplasm division, where two cells are formed. Each of these cells has its own nucleus with identical chromosomes. It is important to note that cytokinesis differs in plants and animals, although the exact details of this difference are not provided in the question.Rate this question:
- 12.
Mass of cancer cells.
Correct Answer
tumorExplanation
The term "tumor" refers to an abnormal growth of cells in the body. In this context, the question is asking for the correct answer that relates to the mass of cancer cells. A tumor is a common term used to describe a mass or lump of cells that can be cancerous or non-cancerous. Therefore, the correct answer to the question is "tumor".Rate this question:
- 13.
The new cells that are produced by cellular division.
Correct Answer
daughter cellsExplanation
When cells undergo cellular division, they give rise to new cells known as daughter cells. Daughter cells are genetically identical to the parent cell and are produced through the process of cell division, such as mitosis or meiosis. This term is commonly used in biology to describe the outcome of cell division, where one cell divides into two or more daughter cells. These daughter cells then continue to grow and carry out their specific functions within the organism.Rate this question:
