A
Which phase of mitosis involves chromosomes lining up in the middle of the cell?
✅ B) Metaphase
What is the main purpose of mitosis?
✅ B) To create new cells for growth and repair
Which phase of mitosis do chromosomes first become visible?
A) Metaphase
B) Anaphase
C) Prophase
D) Telophase
✅ C) Prophase
What is the process by which a eukaryotic cell divides to form two identical daughter cells?
A) Meiosis
B) Mitosis
C) Binary fission
D) Cytokinesis
✅B) Mitosis
How many daughter cells are produced by mitosis?
✅ B) 2
What is the final phase of mitosis?
✅ D) Telophase
Which type of cells undergo mitosis?
✅ B) Somatic cells
In which phase of mitosis does the nuclear envelope break down?
A) Prophase
B) Metaphase
C) Anaphase
D) Telophase
✅ A) Prophase
What structure is responsible for pulling sister chromatids apart during anaphase?
✅ Spindle Fibers
Name the phase of mitosis where the nuclear membrane re-forms around two separate sets of chromosomes.
✅ Telophase
What is the chronological order of stages in mitosis after interphase?
✅ Prophase → Metaphase → Anaphase → Telophase → Cytokinesis
What term describes the division of the cytoplasm wherein the cell separates into two daughter cells indicating the completion of mitosis?
✅ Cytokinesis
What structure holds sister chromatids together?
✅ Centromere
How many phases are in mitosis (excluding interphase)?
✅ Five (5)
How do spindle fibers attach to chromosomes?
✅ They attach to chromosomes at the kinetochore, a structure on the centromere
What is the role of spindle fibers during mitosis?
✅ They pull sister chromatids apart to opposite ends of the cell.
What is the main difference between prophase and metaphase?
✅ In prophase, chromosomes condense and the nuclear envelope breaks down; in metaphase, chromosomes align at the cell's equatorial plane.
A cell is observed under a microscope. The chromosomes are condensed and aligned in the center, but not yet separated. Which phase is this?
✅ Metaphase
Describe what happens during the Anaphase stage in mitosis?
✅ The sister chromatids are pulled apart at the centromere. Spindle fibers shorten, pulling the separated chromatids toward opposite ends (poles) of the cell.
What happens to the chromosomes during prophase?
✅ The chromosomes condense and become more visible.
