Identify the correct match of the type of water given in Column-$I$ and its character in Column-$II$ and select the correct option.

Column-$I$	Column-$II$
$(a)$ Capillary water	$(i)$ Present in the form of hydrated oxides of Silicon and Aluminum
$(b)$ Hygroscopic water	$(ii)$ Goes down through large pores between soil particles and reaches the water table
$(c)$ Combined water	$(iii)$ Held in between small non-colloidal soil particles
$(d)$ Gravitational water	$(iv)$ Held tightly around soil particles by adhesive forces

Water is indispensable for life. What properties of water make it useful for all biological processes on the earth?

Read the following statements and identify the statements for Apoplast and Symplast pathways.
$I -$ Water movement occurs through plasmodesmata.
$II -$ Bulk flow of water occurs due to adhesive and cohesive forces.
$III -$ Water movement occurs through cell walls.
$IV -$ Transmembrane movement occurs near the Casparian strip.
$V -$ Water movement occurs through the cytoplasm.
$VI -$ Movement is relatively faster.
$VII -$ Water movement occurs through intercellular spaces.
Identify the Apoplast and Symplast pathways respectively.
