Animal Cells

• What is the function of the nucleus in an animal cell?

  To enclose the genetic material (DNA).
• Why is the nucleus stained blue in the image of animal cells?

  To make the nuclei visible under the microscope.
• What is the cytoplasm?

  The watery solution inside the cell where chemical reactions take place.
• What role does the cell membrane play in an animal cell?

  It controls the molecules that can enter and leave the cell.
• What are the main organelles found in an animal cell?

  • Nucleus
  • Cytoplasm
  • Cell membrane
  • Mitochondria
  • Ribosomes
• What is the function of mitochondria in an animal cell?

  They are where aerobic respiration takes place.
• Why can't mitochondria and ribosomes be seen under a light microscope?

  Because they are too small.
• What is the function of ribosomes in an animal cell?

  They are the site of protein synthesis.
• Why are proteins important in cells?

  They carry out many functions, including enzyme activity.
• What type of microscope is needed to see ribosomes?

  An electron microscope.
• What are the key functions of the main parts of an animal cell?

  • Nucleus: Encloses genetic material
  • Cytoplasm: Site of chemical reactions
  • Cell membrane: Controls entry and exit of substances
  • Mitochondria: Site of aerobic respiration
  • Ribosomes: Site of protein synthesis
