Mention three similarities

Mention three similarities and two differences between facilitated diffusion and active transport of substances in plants.

(i) Both of them require specific membrane transport proteins.
(ii) The rates may reach a maximum following saturation of the transport proteins.
(iii) They are highly selective for the substances they transport.

Facilitated Diffusion :
It is passive process and does not require energy.
It occurs following concentration gradient
i.e., from higher concentration to lower concentration.

Active Transport :
It requires energy.
It can occur against concentration gradient,
i.e., from lower concentration to higher concentration.
