TOPIC 9 DAY 2 MITOSIS AND CYTOKINESIS

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 stages of mitosis?

Back

The main stages 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 begins to dissolve, and spindle fibers start to form.

Front

What is the role of spindle fibers in mitosis?

Back

Spindle fibers help to separate the chromosomes during cell division by attaching to the centromeres and pulling them apart.

Front

What occurs during metaphase?

Back

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

Front

What is anaphase?

Back

Anaphase is the stage of mitosis 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 divides, resulting in two separate daughter cells.

Front

How many chromosomes do daughter cells have after mitosis?

Back

Daughter cells have the same number of chromosomes as the parent cell; for example, if the parent cell has 18 chromosomes, each daughter cell will also have 18.

Front

What is a centriole?

Back

A centriole is a cylindrical structure that helps organize the assembly of spindle fibers during cell division.
