Write the five stages represented by the abbreviation IPMAT in the correct order.
The letters in IPMAT are already in the correct sequence.
IPMAT stands for Interphase, Prophase, Metaphase, Anaphase, and Telophase in that order. - 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?
This stage is interphase. During interphase, the cell grows, carries out normal functions, and copies its DNA before mitosis begins. - 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?
This is the first mitotic phase after interphase.
The phase shown is prophase. In prophase, chromosomes condense, the nuclear envelope begins to break down, and the spindle apparatus starts forming. - 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?
The word metaphase can be connected with chromosomes meeting in the middle.
This phase is metaphase. The chromosomes line up along the metaphase plate, which is the middle region of the cell. - 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?
This phase is anaphase. The movement is important because it separates identical sister chromatids so each future daughter cell can receive a complete set of chromosomes. - 6
A cell image shows two new nuclei forming around separated chromosomes at opposite ends of the cell. Which phase is this?
Telophase is the final phase listed in IPMAT.
This phase is telophase. During telophase, chromosomes reach opposite poles, nuclear envelopes reform, and the cell prepares to finish dividing. - 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.
Match each event to one letter in IPMAT.
The correct order is DNA is copied, chromosomes condense, chromosomes line up in the middle, sister chromatids separate, and two nuclei form. These events match interphase, prophase, metaphase, anaphase, and telophase. - 8
A student says that anaphase happens before metaphase because chromatids must separate before they can line up. Explain the mistake.
The student is mistaken because chromosomes line up in metaphase before sister chromatids separate in anaphase. The correct order is metaphase first, then anaphase. - 9
During which phase do spindle fibers attach to chromosomes and help arrange them at the center of the cell?
Look for the phase where chromosomes are arranged across the cell's equator.
This happens during metaphase. Spindle fibers attach to chromosomes and help position them along the metaphase plate. - 10
Describe the difference between telophase and cytokinesis.
Telophase is the stage when two nuclei form around the separated chromosomes. Cytokinesis is the process that divides the cytoplasm and physically separates the cell into two daughter cells. - 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.
First identify each cell's phase, then use PMAT order for mitosis.
The correct order is Cell C, Cell A, Cell D, and Cell B. These match prophase, metaphase, anaphase, and telophase. - 12
Why is it important that DNA is copied during interphase before mitosis begins?
DNA must be copied during interphase so that each daughter cell can receive a complete and identical set of genetic information after mitosis and cytokinesis.
