Exploration: The Cell Cycle

Directions
You will evaluate some of these activities yourself, and your teacher may evaluate others. Please save this document before beginning the lesson and keep the document open for reference during the lesson. Type your answers directly in this document for all activities. ________________________________________________________________________________

Self-Checked Activities

Read the instructions for the following activities and type in your responses. At the end of the lesson, click the link on the Summary screen to open the Student Answer Sheet. Use the answers or sample responses to evaluate your own work.

1. Mitosis

You have conducted an experiment following the cell cycle of an animal cell. Each link below leads to a drawing of the slides you viewed from each phase of the cell’s reproduction. Click the link to a slide and identify the subphase of mitosis it shows. Then number the slides 1 to 4 in the order they occur.

Type your response here:

Slide 1 Phase:Order:

Slide 2 Phase:Order:

Slide 3 Phase:Order:

Slide 4 Phase:Order:

How did you do? Check a box below.

 Nailed It! – I included all of the same ideas as the model response on the Student Answer Sheet.

 Halfway There – I included most of the ideas in the model response on the Student Answer Sheet.

 Not Great – I did not include any of the ideas in the model response on the Student Answer Sheet.

2. Comparing Plant and Animal Cell Cycles

Use the links in the lesson to review the cell cycles of a plant cell and an animal cell. Note what happens in each phase and write your comparisons in this table.

Type your response here:

 
Plant Cell
Animal cell
interphase
 
 

mitosis
 
 

cytokinesis
 
 

How did you do? Check a box below.

 Nailed It! – I included all of the same ideas as the model response on the Student Answer Sheet.

 Halfway There – I included most of the ideas in the model response on the Student Answer Sheet.

 Not Great – I did not include any of the ideas in the model response on the Student Answer Sheet.

Teacher-Graded Activities

Write a response for each of the following activities. When you have finished, submit your work to your teacher. Check the rubric at the end of this document to be sure you are meeting the expected criteria for the assignments.

1. Interphase

Use drawing tools on the computer to sketch a cell in the interphase stage of the cell cycle. Label the important parts of the cell in this phase. Check with your teacher to see if you can complete this assignment on paper.

2. Cytokinesis

Use drawing tools on the computer to sketch a plant or animal cell in the cytokinesis phase of the cell cycle. Label the important parts of the cell in this phase. Check with your teacher to see if you can complete this assignment on paper.

After you have completed all the activities, submit this document to your teacher for grading.

Rubrics

These rubrics will be used by your teacher to grade your assignments.
