Mitosis Review

Front

What is mitosis?

Back

Mitosis is the process of cell division that results in two genetically identical daughter cells from a single parent cell.

Front

What are the main phases of mitosis?

Back

The main phases of mitosis are Prophase, Metaphase, Anaphase, and Telophase, often abbreviated as PMAT.

Front

What occurs during Prophase?

Back

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

Front

What happens during Metaphase?

Back

During Metaphase, chromosomes align at the cell's equatorial plane, and spindle fibers attach to the centromeres of the chromosomes.

Front

What is the role of Anaphase in mitosis?

Back

In Anaphase, sister chromatids are pulled apart to opposite poles of the cell, ensuring each daughter cell will receive an identical set of chromosomes.

Front

What occurs during Telophase?

Back

During Telophase, the chromosomes de-condense back into chromatin, the nuclear envelope re-forms around each set of chromosomes, and the cell prepares to divide.

Front

What is the function of centrioles in cell division?

Back

Centrioles help organize the spindle fibers that separate chromosomes during cell division.

Front

Why is mitosis important for multicellular organisms?

Back

Mitosis is crucial for growth, tissue repair, and replacement of damaged or dead cells in multicellular organisms.

Front

What is cytokinesis?

Back

Cytokinesis is the process that follows mitosis, where the cytoplasm of a parental cell divides into two daughter cells.

Front

How does mitosis differ from meiosis?

Back

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