Cell Cycle and Cancer Test

Imagine a rapidly growing plant. If the cells in the plant's stem do not go through the S phase of the cell cycle before mitosis, what might be wrong with the new cells forming the stem?

What are two purposes of the cell cycle?

Beginning with prophase, list the phases of mitosis in order and give a brief description of what happens in each phase.

Tee wants to win a blue ribbon at the fair this year for the largest tomato plants. He would like to compare two new plant foods on his tomato plants to see if they really make the plants grow larger. Tee needs to design an experiment to see which plant food works better. He has three of the same type of tomato plant and they all receive the same amount of sunlight and water and are kept at the same temperature. Tee adds Miracle Grow to plant A, Kate’s Fertilizer to plant B, and he lets plant C grow without any plant food. He measures the growth of the plants every week.

What is the independent variable?

• plant food

• plant growth

• plant without plant food

• amount of water

Why is it important for cells of multicellular organisms to undergo mitosis?

• Mitosis allows for reproduction with male and female gametes.

• Mitosis increases variation within an organism.

• Mitosis produces cells that are different from the original dividing cell.
