Questions and Answers

What is the main function of cells in organisms?

  • Maintaining the shape of the organism
  • Producing energy for the organism
  • Serving as the basic living unit of structure and function (correct)
  • Regulating temperature in the organism

    • How does cell size affect the ability to get materials in and out of a cell?

  • Cells with more irregular shapes are less efficient in material exchange
