Seed swelling

The seeds are used for plant reproduction. Seed structure (undifferentiated tissues, low water content) allows him to easily survive in the unfavorable season of the year in order to germinate in the spring under the right conditions for this. Taken from http://worldofschool.org

Once in the favorable conditions of temperature and humidity, the seed begins to swell, i. e. seed cell protoplasm absorbs water and expands. At the same time develops a considerable force. Swelling force of seeds is used, for example, to disconnect the joints of the skull to isolate the individual bones in their study. Ancient people used the force of swelling of dry wood colloids for splitting stones for construction work. A certain amount of heat is released during the swelling of the seeds. Then, a seed starts to breathe vigorously, so that if the grain at this time lies as a heap, it can easily heat up. Dry seeds are breathing very weak, but if you increase their water content at least for a little, they will begin an intensive breathing. At a water content of 33% (i. e. at full swelling) breathing is greater in 10 000 times than the breath of air-dry seed containing 13% water.
