(D) The process by which seeds absorb water before germination is known as $Imbibition$. $Imbibition$ is a special type of diffusion where water is absorbed by solids (colloids),causing them to increase in volume. In wheat grains,the seed kernel contains starch and proteins that act as hydrophilic colloids,absorbing water and swelling significantly. This swelling creates $Imbibition$ pressure,which helps in breaking the seed coat and allows the seedling to emerge.
