Assignment C-1: Cell Division Gizmo
□ Read the Explorelearning Enrollment Handout in the Introduction materials folder
to learn how you can access Gizmos.
□ Make sure you use a name your instructor can recognize when you log in and
don’t forget to do the 5 question quiz at the end of the Gizmo. They are part of your
mark.
Conduct a search for `cell division gizmo`
Follow the instructions carefully and step by step work through the gizmo and answer the required
questions. Type your answer between the brackets.
Prior Knowledge Questions (Do these BEFORE using the Gizmo.)
1. Cells reproduce by splitting in half, a process called cell division. What do cells need to do between
divisions to make sure that they don’t just get smaller and smaller? <A cell must grow >
2. The genetic information of a cell is carried in its DNA (short for deoxyribonucleic acid). What do cells
need to do between divisions to make sure that a full set of DNA gets passed on to each daughter
cell? <The DNA must be copied so there is a full set of DNA to pass on to each
daughter cell >
Gizmo Warm-up
On the SIMULATION pane of the Cell Division Gizmo™, check that the
Cycle Length is set to 12 hours. Click Play ( ), observe until the
maximum number of cells is shown, and then click Pause ( ).
1. Look at the cells. Do they all look the same? <No >
2. Cells that are in the process of dividing are said to be in mitosis or
cytokinesis. Cells that are not dividing are in interphase.
Check the Magnify box and move the cursor over the cells.
A. Of the 100 cells shown, how many are in the process of dividing? <about 5-10 >
, B. Select the BAR CHART tab, and turn on Show numerical values. How many cells are in the
interphase stage of their life cycle<85>
C. Based on these two observations, would you say that a cell spends most of its life cycle in
interphase or in mitosis/cytokinesis? <Interphase >
Activity A: Get the Gizmo ready:
• Click Reset ( ).
• Select the DESCRIPTION tab.
Phases of the cell
• Click on the right arrow once so that Interphase is
cycle
shown.
Question: What are the stages of the cell cycle?
1. Observe: Click Play and hold the cursor over the cell. Observe the cell as it divides several times.
(This happens quickly!) What do you notice happening during this process? <I noticed that
during interphase, the cell stays here the longest and then once it is ready to
start mitosis, it happens quickly and the rise in cells increases exponentially
every time a cell divides >
2. Summarize: On the DESCRIPTION pane, read about each phase in the cell cycle. In the spaces below,
sketch the cell in each phase and summarize what occurs in your own words.
Phase Sketch Summary
< The cell is preparing for cell division by 3
stages: G1,S and G2 In this stage, the
Interphase
chromatin is duplicated, and organelles are
synthesized >
<The chromosomes are expressed and
Prophase outside the centrioles have spindle fibers
forming and migrate to the ends of the cell>
Metaphase < Then the centromeres attach to the
spindle fibers pulling the chromosomes into
a line>
