Practice identifying and ordering the major stages of the cell cycle and mitosis using the IPMAT sequence.

Read each problem carefully. Use the IPMAT order: Interphase, Prophase, Metaphase, Anaphase, Telophase. Include cytokinesis when the question asks about the final physical division of the cell.

Practice sequencing interphase, prophase, metaphase, anaphase, and telophase

Biology - Grade 9-12

Instructions: Read each problem carefully. Use the IPMAT order: Interphase, Prophase, Metaphase, Anaphase, Telophase. Include cytokinesis when the question asks about the final physical division of the cell.
  1. 1

    Write the five stages represented by the abbreviation IPMAT in the correct order.

  2. 2

    A cell has duplicated its DNA and is growing while preparing for division. Which stage of IPMAT is this, and what happens during this stage?

  3. 3

    A microscope image shows chromosomes becoming visible as condensed structures, the nuclear envelope starting to break down, and spindle fibers beginning to form. Which phase is shown?

  4. 4

    A cell image shows chromosomes lined up across the middle of the cell. Which phase is this, and what is the name of the middle region where chromosomes line up?

  5. 5

    A cell image shows sister chromatids separating and moving toward opposite poles of the cell. Which phase is this, and why is this movement important?

  6. 6

    A cell image shows two new nuclei forming around separated chromosomes at opposite ends of the cell. Which phase is this?

  7. 7

    Put these events in the correct order: chromosomes line up in the middle, DNA is copied, sister chromatids separate, chromosomes condense, two nuclei form.

  8. 8

    A student says that anaphase happens before metaphase because chromatids must separate before they can line up. Explain the mistake.

  9. 9

    During which phase do spindle fibers attach to chromosomes and help arrange them at the center of the cell?

  10. 10

    Describe the difference between telophase and cytokinesis.

  11. 11

    A lab slide shows four cells. Cell A has chromosomes lined up in the center, Cell B has two forming nuclei, Cell C has condensed chromosomes, and Cell D has chromatids moving apart. List the cells in mitosis order.

  12. 12

    Why is it important that DNA is copied during interphase before mitosis begins?
