Cell Cycle Identification Standard(s): 1e: Students know cells divide to increase their numbers through a process of mitosis, which results in two daughter cells with identical sets of chromosomes. (derived from 7th grade Biology standards) Objective: Students will be able to identify the major events that characterize each of the five phases of the cell cycle. Materials: “Cell Cycle Identification” handout scissors color pencils gluestick Instructor’s Direction: 1. Print “Cell Cycle Identification” handout and images of the cell cycle on white paper. (Note: Each page of the cell cycle images have 3 student copies to save paper.) 2. Distribute “Cell Cycle Identification” handout and cell cycle images (strip) to the students. 3. Students have to first identify the correct cell cycle name. 4. Students follow the coloring instructions in the boxes of the handout. 5. Teacher needs to verify that the coloring and cell cycle identification is correct before student can proceed to cut and glue. 6. Students cut and glue the images in the correct location. 7. Students write brief descriptions that best describe the cell cycle event.

In plants, a cell wall forms in the center of the dividing cell.
