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 envelope breaks down, and the 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 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 of a parental cell divides into two daughter cells.

Front

How do plant and animal cells differ in 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 the significance of the cell cycle?

Back

The cell cycle is crucial for growth, development, and repair in multicellular organisms, allowing for the production of new cells.

Front

What is interphase?

Back

Interphase is the phase of the cell cycle where the cell prepares for division, consisting of G1, S, and G2 phases.
