    This is a point on my book :

    At the endodermis ions must be actively taken up to by-pass the Casparian
    band which allows the plant to selectively take up the ions at this point.


    I'm confused as to why its actively transported ? Because when the ions reach the casparian strip, there would be a higher concentration of the ions present there, and a lower concentration in the cytoplasms of the endodermis cells? So why isn't it by diffusion ?
