Diffusion rates are affected by the gradient of concentration,the permeability of the membrane separating them,light and pressure.

Vedclass · Answer

(D) Diffusion is the net movement of molecules from a region of higher concentration to a region of lower concentration. $1$. It is a passive process,meaning it does not require energy expenditure $(ATP)$. $2$. Molecules move in a random fashion. $3$. It is a slow process and does not depend on a 'living system'. $4$. Diffusion rates are affected by the gradient of concentration,the permeability of the membrane separating them,temperature,and pressure. Light does not directly affect the rate of diffusion. Therefore,option $D$ is the incorrect statement.

Column-$I$	Column-$II$
$P$. Diffusion	$I$. Along the gradient, with protein
$Q$. Facilitated transport	$II$. Against the gradient
$R$. Active transport	$III$. Along the gradient, without protein
