Cell Cycle/Mitosis VA 2018 Standards

Front

What is the cell cycle?

Back

The cell cycle is the series of events that take place in a cell leading to its division and duplication (replication). It consists of interphase and the mitotic phase.

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 membrane begins to break down, and spindle fibers start 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 stage where sister chromatids are pulled apart to opposite poles of the cell by the spindle fibers.

Front

What happens during Telophase?

Back

During Telophase, the chromosomes reach the poles, the nuclear membranes reform around each set of chromosomes, and the cell begins to pinch in preparation for division.

Front

What is cytokinesis?

Back

Cytokinesis is the final stage of the cell cycle where the cytoplasm divides, resulting in two daughter cells.

Front

How do plant cells differ from animal cells during cytokinesis?

Back

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

Front

What is interphase?

Back

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

Front

What is the significance of mitosis?

Back

Mitosis is essential for growth, development, and tissue repair in multicellular organisms.
