Examples of bulk flow by a positive hydrostatic pressure gradient and a negative hydrostatic pressure gradient are

Which of the following statements are correct regarding the factors affecting absorption by plants?
$i$. In dicots,the guard cells are dumbbell shaped.
$ii$. The transport of food through phloem is bidirectional.
$iii$. Capillary water is available to plants.
$iv$. Lenticels are small,raised structures composed of compactly arranged complementary cells.
$v$. Stomatal transpiration occurs during day time only.
Choose the correct option:

Define the following terms:
$(1)$ Ascent of sap
$(2)$ Phloem transport

Match the properties of water with their significance:

$(1)$ High viscosity	$(a)$ Temperature of the environment does not affect water
$(2)$ Cohesion	$(b)$ Acts as an efficient solvent
$(3)$ High specific heat	$(c)$ Absorption of mechanical shocks
$(4)$ Polarity	$(d)$ Necessary for the ascent of sap in plants

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 :

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.
