mineral uptake by active transport

• Nitrates

  Needed to make proteins
• Minerals required by plants

  • Nitrates
  • Calcium
  • Magnesium
• Calcium

  Required for cell wall
• Magnesium


  Required for chlorophyll
• Mineral uptake by plants

  1. Absorbed through root hair cells

  2. Via the process of active transport
• Active transport

  Movement of molecules against a concentration gradient using energy from respiration
• Root hair cells

  • Long hair-like extension to increase surface area, helping absorption for mineral uptake
• In waterlogged soil

  Not enough oxygen for respiration, so no energy for active transport/mineral uptake
• Function of root hair cells

  Absorb minerals and water
