Mastering the Phases of Mitosis: An Interactive Quiz

1. What is the role of spindle fibers during cell division?

Spindle fibers have no role in cell division.

Spindle fibers pull chromosomes in half

Spindle fibers make up the cell wall.

Spindle fibers push chromosomes together.

Spindle fibers are responsible for correctly distributing the chromosomes during cell division by pulling them apart to opposite ends of the cell.

Explanation

Spindle fibers are responsible for correctly distributing the chromosomes during cell division by pulling them apart to opposite ends of the cell.

2. What occurs during interphase?

Cell division occurs.

Mitosis begins.

Interphase-chrmosomes are duplicated

Proteins are synthesized.

Interphase is the phase of the cell cycle in which a cell grows, carries out its normal functions, and replicates its DNA in preparation for cell division. Chromosomes are duplicated during this phase, not during cell division, protein synthesis, or during mitosis.

Explanation

Interphase is the phase of the cell cycle in which a cell grows, carries out its normal functions, and replicates its DNA in preparation for cell division. Chromosomes are duplicated during this phase, not during cell division, protein synthesis, or during mitosis.

3. What is the first stage of mitosis?

Telophasechromatids line up in the center of the cell

Anaphasechromosomes align at the cell's equator

Prophasenuclear membrane breaks apart

Interphasecell grows and prepares for division

Prophase is the first stage of mitosis where the nuclear membrane breaks apart allowing the chromatids to condense and become visible.

Explanation

Prophase is the first stage of mitosis where the nuclear membrane breaks apart allowing the chromatids to condense and become visible.

4. During which phase of mitosis do the chromosomes line up in the center, the nuclear membrane disappears, and spindle fibers attach to the chromosomes?

Metaphase-no nuclear membrane-chromosmes line up in centerspindle fibers attach to chromosomes

Telophase-chromosomes arrive at poles-nuclear membrane reforms-spindle fibers disassemble.

Anaphase-sister chromatids separate to opposite poles-spindle fibers contract to pull chromatids apart.

Prophase-chromosomes condense-nuclear membrane disappears-spindle fibers begin to form.

During metaphase, the chromosomes are aligned along the center of the cell, without the nuclear membrane, and the spindle fibers attach to the chromosomes to prepare for their separation towards opposite poles during anaphase. This process is crucial for ensuring the accurate division of genetic material during cell division.

Explanation

During metaphase, the chromosomes are aligned along the center of the cell, without the nuclear membrane, and the spindle fibers attach to the chromosomes to prepare for their separation towards opposite poles during anaphase. This process is crucial for ensuring the accurate division of genetic material during cell division.

5. How many new cells are created through the process of cell division?

1 new cell

2 new cells

4 new cells

3 new cells

In cell division, one cell divides into two new cells through the process of mitosis, resulting in the formation of identical daughter cells.

Explanation

In cell division, one cell divides into two new cells through the process of mitosis, resulting in the formation of identical daughter cells.

6. What happens when a cell undergoes cytokinesis?

Cell undergoes meiosis

Nucleus divides into two daughter nuclei

Cell membrane splitsback to interphase

Cell enters G1 phase

Cytokinesis is the process in cell division where the cytoplasm and cell membrane are divided to create two daughter cells. During this phase, the cell membrane splits back to interphase, separating the newly formed nuclei.

Explanation

Cytokinesis is the process in cell division where the cytoplasm and cell membrane are divided to create two daughter cells. During this phase, the cell membrane splits back to interphase, separating the newly formed nuclei.
