Experiment: Those Swell Seeds | Answers in Genesis
The process of seeds absorbing water is called imbibition. During imbibition, a seed can swell to several times its original size. This swelling can cause tremendous pressure—often over 1,000 pounds per square inch (6900 kPa). Swelling seeds can break rocks and concrete or, in the case of the Cali, rupture a steel cargo ship. This swelling ...

4.6.4: Germination
Germination in Monocots. As the seed germinates, the radicle emerges and forms the first root. In epigeous monocots (such as onion), the single cotyledon will bend, forming a hook and emerge before the coleoptile (Figure 4.6.4.5 4.6.4. 5 ). In hypogeous monocots (such as corn), the cotyledon remains belowground, and the coleoptile emerges first.
