Mitosis and Cell Types Review for the TEST 12/2024

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.

Front

What is the role of the centromere?

Back

The centromere is the region of a chromosome where the two sister chromatids are joined together and where the spindle fibers attach during cell division.

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

What occurs during Metaphase?

Back

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

Front

What is Anaphase?

Back

Anaphase is the phase 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 the difference between plant and animal cells during cytokinesis?

Back

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

Front

What is a chromatid?

Back

A chromatid is one half of a duplicated chromosome, which is joined to its sister chromatid at the centromere.

Front

What is the significance of the cell cycle?

Back

The cell cycle is crucial for growth, development, and repair in organisms, ensuring that cells divide accurately and at the right time.
