Vedclass · Answer

(A) Assertion $(A)$ is correct: Diffusion is a passive,random,and slow process that does not depend on a living system. It is effective only over short distances.Reason $(R)$ is correct: In plants,long-distance transport of water,minerals,and food occurs through the vascular tissues ($xylem$ and $phloem$) using a mass or bulk flow system,which is driven by pressure differences.Since both statements are scientifically accurate,the correct option is $A$.

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

$A-$ Diffusion is a very slow process and is responsible for the short-distance movement of molecules.
$R-$ Water,minerals,and food are generally moved by a mass or bulk flow system.

Assertion: When the ambient temperature is high and soil contains excess of water,the plants tend to lose water in the form of droplets from lenticels.
Reason: Root pressure regulates the rate of loss of water from lenticels.
