D)Both Assertion and Reason are incorrect

Answer 1

Hint: Imbibition causes the swelling up of seed coats and the breaking up of exams in the course of seed germination. Imbibition reasons the water to move to ripen ovules. Imbibition requires two integral conditions, particularly diffusion strain gradient or water achievable gradient between water and imminent.

Complete answer:
Let us have a seem to be on declaration given in question:
Dried seeds of Pea are kept in tin, water is poured over them up to upper level. A lid is put tight over it. After a certain period of time the lid is blown off:
Imbibition entails an internet motion of water in an awareness gradient. So it is considered as a unique type of diffusion. Still, it differs from actual diffusion in two respects, specifically it requires drawing close or adsorbent (i) no membranes are worried in it.
Imbibition is the absorption or adsorption of water by way of the stable and hydrophilic contents of the telephone wall by means of floor attraction, without forming a solution. The water this absorbed is referred to as imbibate, and the substance that imbibed water is called imbibant.

When an approaching is immersed in water, it swells up and develops an inward pressure, known as matrix potential. So the lid falls off. It may additionally be very high in dry seeds and dry wood.

Now let us have a look on given reason:
Due to rapid cell division in Pea seeds:
Due to cell division , the pea size gets increased and it does not swell such that the lid can fall off.
So this reason is wrong.

Hence, the correct answer is option (C)

Note: During inhibition, some kinetic power of water molecules is misplaced as heat. It is called the heat of wetting or heat of hydration. It raises the temperature of the medium. This is the purpose why water turns into heat every now and then when dry seeds are soaked. In passive absorption, cellulose, starch, and pectic compounds of the mobile wall act as imbibes, besides the involvement of the plasma membrane. The root gadget has only a passive position in passive water absorption; it only presents an absorptive surface.
