Cell Cycle and Cancer Concepts

Which statement accurately describes a principle of Modern Cell Theory?

• All living things are composed of cells.

• Cells are the largest units of life.

• Cells can spontaneously generate from non-living matter.

• Only multicellular organisms are made of cells.

How do multicellular organisms primarily increase in size?

• Individual cells grow larger indefinitely.

• Cells absorb more water to expand.

• By producing more cells through division.

• Through the fusion of existing cells.

What two main processes are involved in the creation of new body cells from an existing cell?

• Photosynthesis and respiration.

• Mitosis and cytokinesis.

• Meiosis and fertilization.

• Transcription and translation.

What is a primary characteristic of cancer cells?

• They divide at a slower rate than healthy cells.

• They exhibit uncontrolled and frequent division.

• They always remain securely anchored in their original location.

• They communicate more effectively with healthy cells.

Besides uncontrolled division, what other problematic behavior can cancer cells exhibit?

• They always communicate perfectly with other cells.

• They may fail to securely anchor themselves and travel to other parts of the body.

• They consistently perform normal cell functions.

• They reduce their need for nutrients.

Which of the following is a known risk factor that can contribute to cells becoming cancerous?

• Regular exercise.

• Exposure to certain toxins or radiation.

• A diet rich in fruits and vegetables.

• Adequate sleep.

What type of cancer treatment specifically targets cells that divide frequently?

• Surgical removal of the tumor.

• Physical therapy.

• Chemotherapy.

• Dietary changes.

During which phase of the cell cycle do cells typically spend most of their time growing, replicating DNA, and performing their normal functions?

• Mitosis.

• Cytokinesis.

• Interphase.

• M-phase.

Which of the following phases are collectively known as Interphase in the cell cycle?

• G1, S, and G2 phases

• Prophase, Metaphase, Anaphase, and Telophase

• G1, S, and M phases

• G2 and M phases

What is the main activity of a cell during the G1 phase?

• Replicating its DNA

• Growing in size

• Dividing into two daughter cells

• Preparing for mitosis
