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

Which of the following statements are correct regarding the factors affecting the absorption of water by plants?
$(i)$ In plants,the rate of water absorption is minimum at a soil temperature of $20^{\circ}C$ to $30^{\circ}C$.
(ii) The presence of capillary water is essential in the soil.
(iii) Poorly aerated soil shows a poor absorption rate.
(iv) $A$ low transpiration rate accelerates the rate of absorption of water in irrigated soil.
$(v)$ $A$ high concentration of solutes in soil water reduces the rate of absorption of water.

Which of the following facts proves that the translocation of materials occurs through the phloem?

Transpiration and root pressure cause water to rise in plants by

The process of water exudation through hydathodes is called:

Correct the following statements:
$(a)$ Cells shrink in hypotonic solutions and swell in hypertonic solutions.
$(b)$ Imbibition is a special type of diffusion when water is absorbed by solids—colloids—causing them to increase in volume.
$(c)$ Most of the water flow in the roots occurs via the symplast.
