The Cell Cycle And Mitosis Trivia Quiz! - Quiz


Do you believe you are an expert on the cell cycle and mitosis? The cell cycle or cell-division cycle is the series of events that occur in a cell that causes it to separate into two daughter cells. These events include the duplication of its DNA and some of its organelles. The mitotic phase is complex and highly regulated. This quiz will demonstrate your knowledge of the cell cycle.


Questions and Answers
  • 1. 

    How many steps are in the entire cell cycle?

    • A.

      None

    • B.

      1

    • C.

      4

    • D.

      6

    Correct Answer
    D. 6
    Explanation
    The entire cell cycle consists of six steps: G1 phase, S phase, G2 phase, mitosis, cytokinesis, and G0 phase. Each step plays a crucial role in the cell's growth, replication of DNA, preparation for division, actual division, and resting phase. Therefore, the correct answer is 6.

    Rate this question:

  • 2. 

    What is the longest step of the cell cycle?

    • A.

      Interphase

    • B.

      Prophase

    • C.

      Metaphase

    • D.

      Anaphase

    Correct Answer
    A. Interphase
    Explanation
    Interphase is the longest step of the cell cycle because it consists of three stages: G1 (gap 1), S (synthesis), and G2 (gap 2). During G1, the cell grows and carries out its normal functions. In the S phase, DNA replication occurs, resulting in the duplication of the cell's genetic material. Finally, in G2, the cell continues to grow and prepares for cell division. Overall, interphase is a crucial period for the cell to grow, replicate its DNA, and prepare for division, making it the longest step of the cell cycle.

    Rate this question:

  • 3. 

    How many daughter cells are produced and the end of mitosis?

    • A.

      1

    • B.

      2

    • C.

      3

    • D.

      4

    Correct Answer
    B. 2
    Explanation
    During mitosis, a single cell divides into two identical daughter cells. This process involves several stages, including prophase, metaphase, anaphase, and telophase. At the end of mitosis, the two daughter cells are formed, each containing the same number of chromosomes as the parent cell. Therefore, the correct answer is 2.

    Rate this question:

  • 4. 

    During which phase of the cell cycle is the genetic material copied (replicated)?

    • A.

      Interphase

    • B.

      Prophase

    • C.

      Anaphase

    • D.

      Telophase

    Correct Answer
    A. Interphase
    Explanation
    During the interphase of the cell cycle, the genetic material is copied or replicated. Interphase is the longest phase of the cell cycle and is divided into three stages: G1 phase, S phase, and G2 phase. In the S phase, DNA replication takes place, where the genetic material is duplicated so that each daughter cell will receive a complete set of chromosomes. This is necessary for cell division to occur successfully in the subsequent phases of the cell cycle.

    Rate this question:

  • 5. 

    Click TWO (2) answers that are true about the daughter cells produced by mitosis.

    • A.

      They are identical to the other cell.

    • B.

      They are uniquely different from each other.

    • C.

      They have different amounts of DNA in them.

    • D.

      They are identical to the parent cell that produced them.

    Correct Answer(s)
    A. They are identical to the other cell.
    D. They are identical to the parent cell that produced them.
    Explanation
    The daughter cells produced by mitosis are identical to each other because they result from the division of a single parent cell. Additionally, they are identical to the parent cell that produced them because they contain the same genetic information.

    Rate this question:

  • 6. 

    Which organelle helps directly with cell division?

    • A.

      Mitochondria

    • B.

      Centrioles

    • C.

      Vacuoles

    • D.

      Golgi Body

    Correct Answer
    B. Centrioles
    Explanation
    Centrioles are the organelles that directly assist with cell division. They are found in animal cells and play a crucial role in organizing the microtubules that form the spindle fibers during cell division. The spindle fibers help separate the chromosomes and ensure that each daughter cell receives the correct number of chromosomes. Without centrioles, cell division would not occur properly, leading to genetic abnormalities and potential cell death. Mitochondria, vacuoles, and the Golgi body do not have a direct role in cell division.

    Click ALL the reasons cell reproduction is necessary.

    • A.

      Grow

    • B.

      Learn

    • C.

      Repair (heal)

    • D.

      Develop

    Correct Answer(s)
    A. Grow
    C. Repair (heal)
    D. Develop
    Explanation
    Cell reproduction is necessary for growth because as cells divide, the body can increase in size and add more cells to different tissues and organs. It is also necessary for repair or healing, as damaged or injured tissues can be replaced by new cells. Lastly, cell reproduction is crucial for development, as it allows for the formation of specialized cells and tissues during embryonic growth and maturation.

    Telophase is the final stage of cell division, specifically in mitosis and meiosis. During telophase, the chromosomes reach opposite poles of the cell, and a new nuclear membrane begins to form around each set of chromosomes. In the given options, letter E represents Telophase.

    • F.

      F

    Correct Answer
    D. D
    Explanation
    The letter D represents Prophase. Prophase is the first stage of mitosis, where the chromatin condenses into visible chromosomes, the nuclear envelope breaks down, and the spindle fibers begin to form.

    Rate this question:

  • 12. 

    Which of these would NOT be a reason for cell reproduction?

    • A.

      To grow a baby in a mother's womb

    • B.

      To metabolize

    • C.

      To repair a damaged muscle

    • D.

      To create more unicellular organisms

    Correct Answer
    B. To metabolize
    Explanation
    Cell reproduction is not necessary for metabolism. Metabolism refers to the chemical processes that occur within a living organism to maintain life, such as the breakdown of food for energy and the elimination of waste products. While cell reproduction is essential for growth, repair, and the production of unicellular organisms, it is not directly involved in metabolism.
