Assertion: When dried seeds of pea are placed in a tin and water is added up to their upper level and then a lid is put tightly over it. Within an hour, the lid will be blown off.
Reason: Due to rapid cell division in pea seeds.
Air dried seeds of pea on coming contact with water can develop an imbibition pressure, which is mainly responsible for uptake of water. This imbibition pressure is so great that the lid will be blown off.
