• Active Transport moves substances from a more dilute solution to a more concentrated solution (against a concentration gradient).


  Key words: Moves Substances, dilute solutions to a more concentrated solution.
• Active Transport uses energy released from food in respiration to provide the energy required. 


  Key words: Uses energy released from food, provides energy.
• Active transport allows plant root hair cells to absorb mineral ions required for healthy growth from very dilute solutions in the soil against a concentration gradient. 


  Key Words: Absorb mineral ions, Healthy growth, very dilute solutions, concentration gradient.
