Answer:
The root hair cells have carrier proteins in their cell membranes. These pick up the mineral ions and move them across the membrane into the cell against the concentration gradient . Because active transport moves ions against the concentration gradient into the root hair cells, energy is needed.Plants absorb water from the soil by osmosis. They absorb mineral ions by active transport, against the concentration gradient. Root hair cells are adapted for taking up water and mineral ions by having a large surface area to increase the rate of absorption.
Hello there,
Your correct answer would be "<span> it answers scientific questions using a formal method". So basically, this is basically like a cycle, a scientific question can always come back to be a scientific process, so they can come back at each other also.
Hope this helps.
