Biology - Plant and Animal cells

• What forms a boundary between the cytoplasm and the outside of the cell?


  The cell membrane
• What is the function of the cell membrane?

  It is partially permeable, controlling what enters and exits the cell
• What is the cytoplasm composed of?

  Water and solutes
• Where do chemical/metabolic reactions occur in the cell?

  In the cytoplasm
• What is the primary function of the nucleus?

  It stores DNA and regulates cell activity
• What is the role of the cell wall?

  It is a layer made up of cellulose surrounding the cell membrane
• What do ribosomes produce?

  Proteins
• How do proteins produced by ribosomes affect chemical reactions?


  They speed up chemical reactions
• What do chloroplasts contain that allows them to absorb light energy?

  Chlorophyll
• What is the function of vacuoles in plant cells?

  They store waste, harmful substances, cell sap, sugars, ions, and help maintain cell shape
• What is the primary function of mitochondria?

  To produce energy for the cell
• What are the main differences between animal and plant cells based on their organelles?


  • Animal cells:
  • Nucleus
  • Cell membrane
  • Cytoplasm
  • Mitochondria
  • Ribosomes

  
  

  • Plant cells:
  • Nucleus
  • Cell membrane
  • Cytoplasm
  • Cell wall
  • Chloroplasts
  • Mitochondria
  • Ribosomes
  • Permanent vacuole
• Which organelle is present in plant cells but not in animal cells?

  Cell wall
• Which organelle is responsible for respiration in the cell?

  Mitochondria
• What is stored in the vacuole of a plant cell?

  Waste, harmful substances, cell sap, sugars, ions, and other solutes
• How do chloroplasts contribute to the function of plant cells?


  They absorb light energy for photosynthesis
