Root is the first structure that emerges from the radicle present in seed. It grows rapidly and absorbs water and nutrients from soil. In the next phase, plumule develops into tiny shoot which elongates and comes out of soil.<br \/>\n<strong>Types of germination<\/strong><br \/>\nOn the basis of elongation of hypoctyl and epicotyl, there are two types of germination:<br \/>\n<strong>(i) Epigeal germination .<\/strong><br \/>\nIn epigeal germination, the hypocotyl elongates and forms a hook pulling the cotyledons above the ground. Examples are beans, cotton and papaya.<br \/>\n<strong> (ii) Hypogeal germination <\/strong><br \/>\nIn this germination, the epicotyl elongates and forms the hook. In this type, the cotyledons stay underground. Examples are pea, maize and coconut.<br \/>\n<img loading=\"lazy\" class=\"size-full wp-image-1921 aligncenter\" src=\"https:\/\/murreeroad.org\/Biology10\/wp-content\/uploads\/2020\/07\/Hypogeal-germination.jpg\" alt=\"Hypogeal germination\" width=\"493\" height=\"214\" srcset=\"https:\/\/murreeroad.org\/Biology10\/wp-content\/uploads\/2020\/07\/Hypogeal-germination.jpg 493w, https:\/\/murreeroad.org\/Biology10\/wp-content\/uploads\/2020\/07\/Hypogeal-germination-300x130.jpg 300w\" sizes=\"(max-width: 493px) 100vw, 493px\" \/><br \/>\n<a href=\"https:\/\/murreeroad.org\/Biology10\/unit-14-support-and-movement-long-questions\/\"><img loading=\"lazy\" class=\"alignnone size-full wp-image-1462 aligncenter\" src=\"https:\/\/murreeroad.org\/Biology10\/wp-content\/uploads\/2020\/06\/back_button.png\" alt=\"\" width=\"150\" height=\"45\" \/><\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Q9.\u00a0Explain the germination of seed.
