ACTIVE TRANSPORT

  • LOWER to HIGHER concentration gradient
  • Allows plants to absorb minerals from a dilute solution against a concentration gradient - essential for growth
  • Root hairs give plants a large surface area for absorbing water and minerals from the soil
  • Need mineral ions for healthy growth
  • Concentration of minerals = higher in root hair cells than in soil around them --> can't use diffusion 
  • Active transport needs energy from respiration to make it work
  • Happens in humans, taking
