Amoeba Sisters: Mitosis and Cell Division

What is the main purpose of mitosis?

• To repair damaged cells

• To produce sperm and egg cells

• To make cells grow bigger

• To organize DNA into chromosomes

Which process is responsible for making identical cells?

• Mitosis

• Meiosis

• Interphase

• Cytokinesis

Why is it important to duplicate chromosomes before mitosis?

• To ensure the new cells have the same DNA as the original cells

• To increase the number of chromosomes in the new cells

• To prevent uncontrolled cell growth

• To repair damaged DNA

What happens during prophase?

• The chromosomes condense and become visible

• The chromosomes line up in the middle of the cell

• The chromosomes move away to opposite sides of the cell

• The new nuclei start to form on each side

What is the role of spindles during mitosis?

• To help move the chromosomes to the ends of the cell

• To duplicate the chromosomes

• To split the cytoplasm into two cells

• To form new nuclei

What is the final stage of mitosis?

• Telophase

• Prophase

• Metaphase

• Anaphase

What is the purpose of cytokinesis?

• To split the cytoplasm and complete cell division

• To duplicate the DNA

• To organize DNA into chromosomes

• To repair damaged cells

What is the term for uncontrolled cell growth?

• Cancer

• Mitosis

• Meiosis

• Interphase

Why is understanding mitosis important for growth and repair?

• Because growth and repair require more cells to be made

• Because mitosis helps organize DNA into chromosomes

• Because mitosis prevents uncontrolled cell growth

• Because mitosis duplicates the DNA

What is the total number of chromosomes in most human body cell nuclei?

• 46

• 92

• 23

• 69
