Unit 4 Cell Division Summative Assessment

Front

What is cell division?

Back

Cell division is the process by which a parent cell divides into two or more daughter cells. It is essential for growth, development, and repair in organisms.

Front

What are the two main types of cell division?

Back

The two main types of cell division are mitosis and meiosis. Mitosis results in two identical daughter cells, while meiosis produces four genetically diverse gametes.

Front

Define mitosis.

Back

Mitosis is a type of cell division that results in two daughter cells, each with the same number of chromosomes as the parent cell, used for growth and repair.

Front

What is meiosis?

Back

Meiosis is a specialized form of cell division that reduces the chromosome number by half, producing four genetically diverse gametes for sexual reproduction.

Front

What is the significance of the cell cycle?

Back

The cell cycle is crucial for regulating cell division, ensuring proper growth, development, and maintenance of tissues in multicellular organisms.

Front

List the phases of mitosis.

Back

The phases of mitosis are prophase, metaphase, anaphase, and telophase.

Front

What happens during prophase?

Back

During prophase, the chromatin condenses into visible chromosomes, the nuclear envelope breaks down, and the spindle apparatus begins to form.

Front

Explain the role of spindle fibers in cell division.

Back

Spindle fibers are structures that help separate chromosomes during cell division by attaching to the centromeres and pulling them apart to opposite poles.

Front

What is cytokinesis?

Back

Cytokinesis is the final stage of cell division where the cytoplasm divides, resulting in two separate daughter cells.

Front

How does meiosis contribute to genetic diversity?

Back

Meiosis contributes to genetic diversity through processes like crossing over and independent assortment, which shuffle genetic material between homologous chromosomes.
