Cell Growth & Reproduction

During the interphase stage of the cell cycle,

• the cell's chromosomes are duplicated.
• the cell's chromosomes condense into rod-like structures.
• the cell divides into two identical daughter cells.
• the cell divides into two unique daughter cells.

Cytokinesis is a process that occurs during the cell cycle.  During cytokinesis,

• the cytoplasm is divided to form two separate cells.
• the cell grows and performs normal life processes.
• the chromosomes of the cell are duplicated.
• the nuclear material of the cell is divided.

Mitosis and meiosis are methods of cell division.
Which of the following is true of these two methods?

• Mitosis involves only one division, while meiosis involves two divisions.
• Meiosis involves one division, while mitosis involves two divisions.
• Meiosis involves two or more divisions, while mitosis involves exactly two divisions.
• Mitosis involves two or more divisions, while meiosis involves exactly two divisions.

Which phase of mitosis is represented in the diagram?

• telophase
• anaphase
• metaphase
• prophase

Which of the following occurs during the interphase stage of the cell cycle?
I. DNA is replicated.
II. The cell divides.
III. The cell grows in size.

• I and III only
• I, II, and III
• II only
• I and II only

How are the processes of mitosis and meiosis similar to each other?

• Both processes result in the same number of cells produced.
• Both processes begin with similar events, including chromosome replication.
• Both processes involve only one division of cellular materials.
• Both processes end with the same number of chromosomes present in each cell.

Cellular reproduction in multicellular organisms occurs through the process of mitosis.  What is the purpose of mitosis?

• to replace old cells such as red blood cells
• to replace old chromosomes
• to form gametes (e.g. sperm and ova)
• to form new somatic cells
