(C) Imbibition is a special type of diffusion where water is absorbed by solids (colloids),causing them to increase in volume.For the process of imbibition to occur,two conditions are mandatory: $1$. There must be a water potential gradient between the absorbent (e.g.,seed) and the liquid imbibed (e.g.,water).$2$. There must be an affinity between the adsorbent and the liquid.Option $A$ is incorrect as it is a process,not a barrier.Option $B$ is incorrect because imbibition pressure is essential for the initial swelling of seeds during germination.Option $D$ is incorrect because imbibition is a short-distance transport process,whereas long-distance transport occurs via the xylem.
