During which process in leaves is the water potential positive?

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.

The ringing experiment is related to:

Match the following:

Column-$I$	Column-$II$
$(P)$ Active absorption	$(1)$ Loss of water
$(Q)$ Osmotic pressure	$(2)$ Plasmolysis
$(R)$ Stomata	$(3)$ Minerals
	$(4)$ Solute concentration

Give differences between:
$(1)$ Diffusion and Osmosis
$(2)$ Transpiration and Evaporation

Differentiate between apoplast and symplast pathways of water movement. Which of these would need active transport?
