Cell cycle worksheet - Name: Date: Period: The Cell Cycle Coloring ... - Free Printable

This is a "Cell Cycle Coloring Worksheet" that requires you to label the different phases of the cell cycle and color them according to specific instructions. Let's break down the task into two parts: labeling and coloring.

Part 1: Labeling the Diagram

The worksheet provides a list of labels to place on the diagram. The cell cycle is typically divided into two main parts: Interphase (which includes G1, S, and G2 phases) and the Mitotic Phase (M Phase) (which includes mitosis and cytokinesis).

Here’s how to assign the labels based on standard biological knowledge:

- Interphase: This is the longest phase where the cell grows and prepares for division. It consists of:
- G1 - cell grows: The first gap phase.
- S-DNA replication: The synthesis phase where DNA is copied.
- G2 - prepares for mitosis: The second gap phase where the cell prepares for division.

- Mitosis: This is the process of nuclear division, which is further divided into four stages:
- Prophase
- Metaphase
- Anaphase
- Telophase

- Cytokinesis: The physical division of the cytoplasm, which usually occurs at the end of mitosis.

- Cell division (M Phase): This term often refers to the entire mitotic phase, including both mitosis and cytokinesis.

In the diagram, you will need to identify the large sections and smaller segments within the circle to place these labels correctly.

Part 2: Coloring the Diagram

The instructions specify colors for different phases and arrows:

- G1 phase: Color BLUE
- S phase: Color YELLOW
- G2 phase: Color RED
- Stages of mitosis: Color ORANGE
- Arrows indicating interphases: Color GREEN
- Arrow indicating mitosis: Color PURPLE
- Arrow indicating cytokinesis: Color YELLOW

Solution Steps:

1. Identify the Phases in the Diagram:
- Look at the circular diagram. The largest section is likely Interphase, which should be divided into G1, S, and G2.
- The smaller section is Mitosis, which may be subdivided into Prophase, Metaphase, Anaphase, and Telophase.
- There may be a small segment or arrow for Cytokinesis.

2. Label Each Section:
- Place “G1 - cell grows” in the first part of Interphase.
- Place “S-DNA replication” in the middle part of Interphase.
- Place “G2 - prepares for mitosis” in the last part of Interphase.
- Place “Prophase,” “Metaphase,” “Anaphase,” and “Telophase” in the respective segments of Mitosis.
- Place “Cytokinesis” in the appropriate segment or arrow.
- You can also label the entire Interphase section as “Interphase” and the Mitosis section as “Mitosis” or “Cell division (M Phase).”

3. Color According to Instructions:
- Color the G1 section BLUE.
- Color the S section YELLOW.
- Color the G2 section RED.
- Color all the mitosis stages (Prophase, Metaphase, Anaphase, Telophase) ORANGE.
- Color the arrows that point to G1, S, and G2 (interphases) GREEN.
- Color the arrow pointing to the mitosis stages PURPLE.
- Color the arrow pointing to cytokinesis YELLOW.

By following these steps, you will have successfully labeled and colored the cell cycle diagram according to the worksheet instructions.
