Some monocots, such as grasses, have [[hypogeal germination|hypogeal emergence]], where the mesocotyl elongates and pushes the coleoptile (which encloses and protects the shoot tip) toward the soil surface.{{sfn|Radosevich et al|1997|loc=[https://books.google.com/books?id=XA1ioKqctwwC&pg=PA149 p.&nbsp;149]}} Since elongation occurs above the cotyledon, it is left in place in the soil where it was planted. 
Many dicots have [[epigeal germination|epigeal emergence]], in which the hypocotyl elongates and becomes arched in the soil. As the hypocotyl continues to elongate, it pulls the cotyledons upward, above the soil surface.
