cell structure

• What type of cells are animals made up of?

  Eukaryotic cells
• What is a defining feature of eukaryotic cells?

  They have a nucleus and other membrane-bound structures
• What is the function of the cell membrane?

  It controls the entry and exit of materials
• What is the role of mitochondria in a cell?

  They contain enzymes for respiration and release energy
• What are ribosomes responsible for?

  Protein synthesis
• What is the cytoplasm and its function?

  It is a jelly-like material where many chemical reactions occur
• How does the structure of the nucleus relate to its function?

  It contains genetic material, including DNA, which controls cell activities
• Why are most cells specialized?

  They are adapted for specific functions
• What are the main components of an animal cell?

  • Cell membrane
  • Cytoplasm
  • Nucleus
  • Mitochondria
  • Ribosomes
• How do light and electron microscopes differ in viewing cells?

  • Light microscopes can view mitochondria but not in detail.
  • Ribosomes can only be seen with an electron microscope.
• What is the relationship between cell structure and function in animal cells?

  • Cell membrane: controls movement of substances
  • Cytoplasm: site of chemical reactions
  • Nucleus: controls cell activities
  • Mitochondria: energy production
  • Ribosomes: protein synthesis
