Once you have completed your experiment design, have your instructor review it before proceeding. Design an experiment which will allow you to test the effects of mechanical seed damage on imbibition. Be sure to include all steps in the scientific process in your design. Once you have completed your experiment design, have your instructor review it before proceeding. The first step in the germination of a seed is imbibition , or water uptake.
Seeds absorb water primarily through the micropyle.
Respiration within the seed also increases with water intake. Since respiration is essential for cell division to occur, oxygen must be present for seeds to germinate. These are transported to the embryo, where some are respired to provide energy and others are used in the synthesis of protein, starch, and cellulose. Water and oxygen are necessary for the enzymes to break down the seed's reserves. The seed cells enlarge.
