Uptake and transport of water and ions — practice question

When plants grow in soil that is saturated with water, their roots do not receive enough oxygen. How will the functions of root hairs be affected under these conditions?

  • Auptake of nitrate ions slowed down; uptake of water slowed down
  • Buptake of nitrate ions slowed down; uptake of water unaffected
  • Cuptake of nitrate ions unaffected; uptake of water slowed down
  • Duptake of nitrate ions unaffected; uptake of water unaffected
