Vedclass · Answer

(B) $\Rightarrow$ When evaporation is low and excess water collects in the form of droplets around special openings of veins near the tip of grass blades and leaves of many herbaceous plants,this water loss in its liquid phase is known as guttation.$\Rightarrow$ Guttation occurs due to high root pressure,which pushes water out through specialized pores called hydathodes.$\Rightarrow$ Root pressure can at best,only provide a modest push in the overall process of water transport.
