Q. When pea seeds and wheat grains are soaked in water, pea seeds showed more swelling than the wheat. The reason is
A) Imbibitions capacity of proteins is more than that of starch
B) Presence of less hydrophilic colloids in the wheat grains
C) Cell membrane of pea seeds is more permeable
D) Cell wall of wheat grains are less permeable
Explanation
Pea seeds contain protein, while wheat contains starch, the imbibition capacity of proteins is more than that of starch. That is why, pea seeds imbibe more water and show more swelling than those of wheat grains.
