Why is it beneficial to plants that soil particles have negatively-charged surfaces?  

A.  It helps maintain the water potential of the soil.
B.  They attract positively-charged ions and prevent them from being washed deep into the soil.
C.  Negatively-charged ions are pushed towards the roots.
D.  Toxic metals are trapped and kept away from the plants.
E.  They capture negatively-charged ions.


B.  They attract positively-charged ions and prevent them from being washed deep into the soil.

Many of the nutrients that plants obtain from the soil are positively charged. These nutrients are attracted to the negative charges of the soil particles. This attraction keeps the nutrients from leaching deeper into the soil or washing away.
