Your friend should use Model A to describe the process of mitosis because it visually illustrates each key stage, making the complex process easier to understand. The sequential images demonstrate how the chromosomes behave during mitosis, from their alignment to their separation and the eventual division of the cell. This visual representation can help your friend's sibling grasp the physical changes that occur during each phase, enhancing their comprehension of the topic. In contrast, Model B provides more abstract information about the cell cycle but lacks the detailed, step-by-step visuals that can reinforce learning through observation. Therefore, Model A is more effective for conveying the dynamic nature of mitosis.
Use the two images to complete the activity.
Model A
The first stage shows a nucleus inside a cell. The second stage shows the nucleus consisting of two pairs of chromosomes with microtubules. The third stage shows the chromosomes lining up with the help of spindles. The fourth stage shows the chromosomes vertically lined up and both the microtubules are attached to each chromosome through the spindles. The fifth stage shows both the microtubules pulling and dividing the chromosomes in half, forming two sets of chromosomes. The sixth stage shows the cell getting divided into two parts. The seventh stage shows two separate cells, each with its own nucleus.
Model B
The cell cycle begins with interphase, where the cell takes approximately 10 hours to grow. If it passes the G1 checkpoint, the DNA duplication starts and goes on for approximately eight hours. The cell further grows for approximately four hours. After passing the G2 checkpoint, the process of mitosis takes place, which takes approximately one to two hours. The phases during mitosis are prophase, metaphase, anaphase, telophase, and cytokinesis. After cytokinesis, the daughter cells enter interphase, and the cycle gets repeated.
Your friend wants to describe what happens during mitosis to a sibling. In three to five sentences, construct an argument on why they should use Model A to describe the process.
