Questions and Answers

What is the primary function of the nucleus in a cell?

  • To digest food and cell debris
  • To convert food into usable energy
  • To serve as the control center of the cell (correct)
  • To package and distribute proteins

    • What is the difference between smooth and rough endoplasmic reticulum (ER)?

  • Smooth ER lacks ribosomes, while rough ER has ribosomes on its surface (correct)
  • Smooth ER is found in the nucleus, while rough ER is found in the cytoplasm
  • Smooth ER is responsible for transporting substances throughout the cell, while rough ER is involved in digestion
  • Smooth ER is involved in protein synthesis, while rough ER is involved in lipid synthesis
