Water is lost as liquid from the plant body in:

Given below are two statements in relation to the limitations of the capillarity theory of water transport in plants.
Statement $I$: Xylem, i.e., the capillarity tube, must be with closed end walls and not hollow.
Statement $II$: The capillarity tube, i.e., xylem, is not in direct contact with soil water and contains a barrier of root cells between the xylem and soil water.
In the light of the above statements, choose the most appropriate answer from the options given below:

If $T = \text{True}$ and $F = \text{False}$, then select the correct option for the following statements:
$1.$ Diffusion is a passive process.
$2.$ $\Psi_S$ (solute potential) is always negative.
$3.$ Osmosis does not depend on a pressure gradient.
$4.$ Mycorrhiza is a symbiotic association of fungus and algae.

Match List $I$ with List $II$ :

List $I$	List $II$
$A$. Cohesion	$I$. More attraction in liquid phase
$B$. Adhesion	$II$. Mutual attraction among water molecules
$C$. Surface tension	$III$. Water loss in liquid phase
$D$. Guttation	$IV$. Attraction towards polar surfaces

Choose the correct answer from the options given below :

$A$. Much of the nitrogen in xylem sap is carried in organic form.
$B$. In phloem,the movement of nutrients is always unidirectional.

Choose true and false statements from the following and select the correct option from the set $(A-D)$ given below:
$I.$ Diffusion is an important process of transport in plants since it is the only means for gaseous movement within the plant body.
$II.$ In active transport,pumps are proteins that use energy to carry substances across the cell membrane against the concentration gradient.
$III.$ In facilitated diffusion,special proteins help hydrophilic substances to be transported across the membrane.
$IV.$ In diffusion,molecules move against the concentration gradient in a random manner.
$V.$ Facilitated diffusion is faster than active transport.
