Gizmos Student Exploration Cell Division

Name: Date: i/v/21

Student Exploration: Cell Partition

Directions: Follow the instructions to go through the simulation. Respond to the questions and

prompts in the orange boxes.

Vocabulary: cell division, centriole, centromere, chromatid, chromatin, chromosome, cytokinesis, DNA,

interphase, mitosis

Prior Knowledge Questions (Do these BEFORE using the Gizmo.)

1. Cells reproduce by splitting in half, a procedure called cell segmentation. What do cells need to do between

divisions to make sure that they don't but get smaller and smaller?

They need to 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 Deoxyribonucleic acid gets passed on to each daughter cell?

The Deoxyribonucleic acid has to exist copied and then in that location is a full set of DNA to be passed on to each

daughter cell.

On the SIMULATION pane of the Cell Division Gizmo, check that the Bicycle

Length is set to 12 hours. Click Play ( ), detect until the maximum number of

cells is shown, and and then click Pause ( ).

1. Look at the cells. Do they all look the same? yes

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.

Cheque the Magnify box and movement the cursor over the cells.

A. Of the 100 cells shown, how many are in the process of dividing?

20 cells

B. Select the BAR CHART tab, and turn on Show numerical values. How many cells are in the

interphase stage of their life cycle? 80 cells

C. Based on these ii observations, would you say that a jail cell spends almost of its life cycle in

interphase or in mitosis/cytokinesis? interphase
