Mitosis and Meiosis quiz

What processes occur through mitosis?

• Cell division for reproduction

• Growth, repair, and development in the embryo

• Photosynthesis in plants

• Protein synthesis in cells

What happens during prophase of mitosis?

• Chromatin condenses into chromosomes, the nuclear envelope breaks down, and the mitotic spindle begins to form.

• Chromosomes align at the cell's equator and are pulled apart by spindle fibers.

• The cell undergoes cytokinesis, dividing the cytoplasm into two daughter cells.

• The DNA is replicated, resulting in two identical copies of each chromosome.

What is cytokinesis?

• Cytokinesis is the process of DNA replication during cell division.

• Cytokinesis is the final stage of the cell cycle where the cytoplasm of a parental cell is divided into two daughter cells.

• Cytokinesis is the phase where chromosomes align at the cell's equator.

• Cytokinesis is the stage where the nuclear envelope breaks down.

What is the function of the centrosome?

• It synthesizes proteins for the cell.

• It organizes microtubules and is crucial for the formation of the mitotic spindle.

• It stores genetic information in the nucleus.

• It regulates the cell cycle and apoptosis.

What is the correct order of stages in mitosis?

• Prophase, Metaphase, Anaphase, Telophase

• Metaphase, Prophase, Telophase, Anaphase

• Anaphase, Telophase, Prophase, Metaphase

• Telophase, Anaphase, Metaphase, Prophase

What is the difference between mitosis and meiosis?

• Mitosis results in two identical daughter cells, while meiosis results in four genetically diverse gametes.

• Mitosis results in four identical daughter cells, while meiosis results in two genetically diverse gametes.

• Mitosis and meiosis both result in two identical daughter cells.

• Mitosis results in two genetically diverse gametes, while meiosis results in four identical daughter cells.

What occurs during telophase?

• The chromosomes condense and the nuclear envelope breaks down.

• The chromosomes de-condense, the nuclear envelope re-forms, and the cell prepares to divide.

• The cell undergoes cytokinesis and divides into two daughter cells.

• The DNA is replicated and the spindle fibers are formed.

What is a centriole?

• A structure that helps in photosynthesis.

• A cylindrical structure involved in cell division, helping to organize the mitotic spindle.

• A type of protein found in the cell membrane.

• A small organelle responsible for energy production.

What is the role of the spindle fibers?

• They help in the formation of the nuclear envelope.

• They assist in the separation of chromosomes during cell division by attaching to the centromeres.

• They are responsible for the synthesis of DNA during replication.

• They play a role in the transport of nutrients within the cell.

What is the significance of crossing over in meiosis?

• It leads to genetic variation in daughter cells.

• It ensures the production of identical daughter cells.

• It occurs only in mitosis, not meiosis.

• It prevents genetic disorders in offspring.
