Understanding Mitosis: A Journey Through Cell Division

What is the process called that allows a cell to divide and create a copy of itself?

• Photosynthesis

• Respiration

• Meiosis

• Mitosis

During which stage do chromosomes first become visible?

• Telophase

• Anaphase

• Metaphase

• Prophase

What happens to the nuclear membrane during prophase?

• It duplicates

• It thickens

• It becomes more visible

• It begins to break down

What structures attach to chromosomes and help align them in the middle of the cell during mitosis?

• Centrioles

• Chromatids

• Spindle fibers

• Nuclear membrane

Where do chromosomes align during metaphase?

• At the cell poles

• Outside the cell

• Along the cell membrane

• In the middle of the cell

What is the role of spindle fibers during mitosis?

• To duplicate DNA

• To create new cells

• To break down the nuclear membrane

• To move chromosomes around the cell

In which stage do sister chromatids begin to separate and move towards opposite poles?

• Anaphase

• Metaphase

• Prophase

• Telophase

What marks the end of telophase?

• Chromosomes aligning at the cell equator

• The complete separation of sister chromatids

• The disappearance of spindle fibers

• The beginning of cytokinesis

During which phase do the nuclear membranes begin to re-form?

• Telophase

• Anaphase

• Prophase

• Metaphase

What significant event occurs during cytokinesis?

• Nuclear membrane re-forms

• The cell begins to divide into two new cells

• Spindle fibers disappear

• Chromosomes become visible
