Unit 4 Cell Cycle Review

Front

What is the purpose of cell division in organisms?

Back

Cell division is necessary for growth, repair of damaged cells, and replacement of dying cells.

Front

What is the first phase of mitosis called?

Back

Prophase

Front

What phase follows metaphase in mitosis?

Back

Anaphase

Front

Which phase of the cell cycle does the cell spend the most time in?

Back

Interphase

Front

What is the phase of mitosis where chromosomes align in the center of the cell?

Back

Metaphase

Front

What is cytokinesis?

Back

Cytokinesis is the process where the cytoplasm of a parental cell divides into two daughter cells after mitosis.

Front

Define interphase.

Back

Interphase is the phase of the cell cycle where the cell spends most of its time, preparing for division by growing and replicating its DNA.

Front

What occurs during prophase?

Back

During prophase, chromatin condenses into visible chromosomes, the nuclear envelope breaks down, and spindle fibers begin to form.

Front

What is the role of spindle fibers during mitosis?

Back

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

Front

What happens during telophase?

Back

During telophase, the chromosomes reach the poles of the cell, the nuclear envelope re-forms around each set of chromosomes, and the chromosomes begin to de-condense.
