2.1 Mitosis 25

Front

What is mitosis?

Back

Mitosis is the process by which a multi-cellular organism divides its cells to replace damaged or dead cells, resulting in two identical daughter cells.

Front

What is the main purpose of mitosis in multi-cellular organisms?

Back

The main purpose of mitosis is to enable growth, repair damaged tissues, and replace old cells.

Front

What are the main phases of mitosis?

Back

The main 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 spindle fibers begin to form.

Front

What occurs 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 Anaphase?

Back

Anaphase is the phase where sister chromatids are pulled apart to opposite poles of the cell.

Front

What happens during Telophase?

Back

During Telophase, the chromosomes reach the poles, the nuclear envelope re-forms around each set of chromosomes, and the chromosomes begin to de-condense.

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

What is interphase?

Back

Interphase is the phase of the cell cycle where the cell prepares for mitosis, including DNA replication and cell growth.

Front

How does mitosis differ from meiosis?

Back

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