YEAR 8

• Cell Membrane


  Semi-permeable barrier controlling cell movement of substances
• Chloroplasts


  Organells found in plant cells responsible for photosynthesis and producing glucose and ATP
• Photosynthesis


  Conversion of light energy into glucose using water and carbon dioxide
• Cell Membrane vs Cell Wall

  Cell membrane is semi-permeable and flexible, found in both plant and animal cells, while cell wall is rigid, plant-cell exclusive, and provides support and protection.
• Cell Wall Function


  Provides support, protection, transportation, mechanical stress resistance, and cell shape maintenance.
• Cell Wall Types


  Primary cell wall, secondary cell wall, middle lamella, cuticle, and pectin cell wall types.
• Primary vs Secondary Cell Wall

  Primary cell walls form early, are thin, and provide basic support, while secondary cell walls form later, are thicker, and provide additional strength and rigidity.
