Water logging occurs in

If you are provided with two tubes ($A$ and $B$),where one is narrow and the other is relatively wider,and if both are immersed in a beaker containing water as shown in the figure. Why does $B$ show higher water rise than $A$?

Which property of water allows planktons to move freely on the water surface?

Differentiate between the following:
Apoplast and Symplast pathways of movement of water in plants.

Match the following columns:

Column-$I$	Column-$II$
$P$. Cohesion	$I$. Water molecules are attracted to each other more in the liquid phase than in the gaseous phase.
$Q$. Adhesion	$II$. Attraction of water molecules to polar surfaces.
$R$. Surface Tension	$III$. Mutual attraction between water molecules.

Which one of the following is not a part of the symplast pathway?
