Questions and Answers

What is a primary purpose of cell division in organisms?

  • To enhance the efficiency of waste removal
  • To increase the size of individual cells
  • To enable reproduction and growth (correct)
  • To facilitate the transfer of nutrients between cells
  • Which of the following best describes the number of divisions that occur during the cell cycle?

  • There are two distinct divisions in the process
  • Only one division occurs regardless of cell type

    Study Notes

    Purpose

    • Essential roles in a variety of biological processes.
    • Contribute to homeostasis by maintaining balance within organisms.

    Number of Divisions

    • Divisions can vary greatly; common categorizations include unicellular and multicellular.
    • Multi-cellular organisms typically have specialized cell types.

    Function in Organisms

    • Cells are the fundamental unit of life, performing vital functions like metabolism, energy production, and waste elimination.
    • Different cell types are specialized for tasks such as reproduction, nutrient absorption, and immune response.
    • Organ systems are composed of tissues, which are groups of similar cells working together for a specific function.
