Division Read pgs. 55-63 in your textbook, then answer the questions.

This section explains how cells grow and divide.

Use Target Reading Skills As you read, make a cycle diagram that shows the events in the cell cycle, including the phases of mitosis. Write each event in a separate circle. The Cell Cycle

Cell Division (continued) Stage 1: Interphase 1.

The regular sequence of growth and division that cells undergo is called the ________________________.

2.

List three things that the cell is doing during interphase. a. _____________________________________________________________________ b. _____________________________________________________________________ c. _____________________________________________________________________

3.

Circle the letter of the specific process during which the cell copies its DNA. a. interphase b. cytokinesis c. replication d. division

Stage 2: Mitosis 4.

Circle the letter of each sentence that is true about mitosis. a. The cell makes a copy of its DNA. b. The cell membrane pinches in around the middle of the cell. c. The cell’s nucleus divides into two new nuclei. d. One copy of DNA is distributed into each daughter cell.

Match the phases of mitosis with the events that occur in each. Event ____ 5. The centromeres split and the chromatids separate. ____ 6. The chromatin condenses to form chromosomes. ____ 7. A new nuclear envelope forms around each region of chromosomes.

Phase a. prophase b. metaphase c. anaphase d. telophase

____ 8. The chromosomes line up across the center of the cell.
