Active Transport
Active transport moves substances from a more dilute solution to a more concentrated solution, requiring energy from respiration.
Do you know why active transport requires energy?
What is Active Transport?
"Active transport is the process of moving substances against a concentration gradient, requiring energy from respiration."
Diffusion is the net movement of particles:
Choose the correct explanation: how are root hair cells adapted for absorbing water and mineral ions?

Active transport moves substances:
Transport Against Gradients
Active transport allows mineral ions to be absorbed from dilute soil solutions into plant root hairs.
It is also used to absorb sugar molecules from the gut into the blood when the blood concentration is already high.
Unlike diffusion and osmosis, active transport moves particles against the concentration gradient.
