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, each with the same number of chromosomes as the 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 break down, and the spindle fibers start to form.

Front

What is metaphase?

Back

Metaphase is the stage of mitosis where chromosomes align at the cell's equatorial plane, and spindle fibers attach to the centromeres.

Front

What occurs during anaphase?

Back

During anaphase, sister chromatids are pulled apart to opposite poles of the cell by the spindle fibers.

Front

What happens in telophase?

Back

In 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

How does cytokinesis differ in plant and animal cells?

Back

In animal cells, cytokinesis occurs through the formation of a cleavage furrow, while in plant cells, a cell plate forms to separate the two daughter cells.

Front

What is a centriole?

Back

A centriole is a cylindrical structure that helps organize the mitotic spindle during cell division.

Front

What are spindle fibers?

Back

Spindle fibers are protein structures that help separate chromosomes during mitosis.
