Identify the following process and choose the correct option.

$A$ plant with well-washed roots was placed in a beaker of water diluted with red ink. The red colour travelled up the stem and into the leaf veins. Which of the following is the explanation for the uptake of red ink into the roots?

Define the following terms:
$(1)$ Antiport
$(2)$ Active transport

Match the following columns correctly:

Column-$I$	Column-$II$
$(a)$ Passive transport	$(p)$ Movement from higher concentration to lower concentration, no energy required
$(b)$ Active transport	$(q)$ Movement along the concentration gradient, requiring carrier proteins
$(c)$ Facilitated diffusion	$(r)$ Movement against the concentration gradient, requiring energy
$(d)$ Osmosis	$(s)$ Diffusion of solvent molecules across a semi-permeable membrane

Identify a type of molecular movement which is highly selective and requires special membrane proteins,but does not require energy.

Compare the following processes of transport and choose the correct option:

$S.no.$	Property	Facilitated diffusion	Active Transport	Simple Diffusion
$I.$	Highly specific	Yes	Yes	No
$II.$	Energy as $ATP$	No	Yes	No
$III.$	Saturation point reached when all carrier proteins are used	Yes	Yes	No
$IV.$	Require transport proteins	Yes	Yes	No
