    Need help with this question:


    Plants exchange substances with the environment.

    Plant roots absorb water mainly by osmosis.
    Plant roots absorb ions mainly by active transport.

    Explain why roots need to use the two different methods to absorb water and ions.[4 Marks]

    Thanks!!!

    It's because the concentration of soil ions is less than the concentration in root cells, meaning that energy in the form of ATP (Adenosine Triphosphate) is required for the ions to move. Also, The concentration of water is also higher in the soil, meaning that water will move down the concentration gradient.

    Brief answer but I hope this helps!
