Analogy type questions:
$(1)$ Stomata : Transpiration :: Hydathode : ..........
$(2)$ Phloem : Translocation of sugars :: Xylem : ..........

$A.$ Most researchers agree that water is mainly 'pulled' upward through the plant, where transpiration is the driving force.
$B.$ Less than one percent of water reaching the leaves is used in plant growth and photosynthesis.
$C.$ Cobalt chloride paper turns blue on absorbing water.

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

Guttation usually occurs when the plant is put

Give differences between:
$(1)$ Osmotic Pressure and Osmotic Potential
$(2)$ Diffusion and Imbibition

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:
