What do you mean by epigeal germination?
the cotyledons come up above the soil surface
Define and explain types of germination?
There are three types of germination 1.Hypogeal germination and epigeal germination and Cleistogeal germination. Hypogeal Germination: In this kind of Germination, the seed leaves or the cotyledons remain under the surface of soil. example: pea seeds - Epigeal Germination: In this type of Germination, the seed leaves grow above the ground on the new shoot. example: ash tree -Cleistogeal Germination: A special leaf that has a central umbrella like stalk forms above the ground which protects the shoot from any damage. So the development of the shoot can not be seen.
What is the hypocotyl of an adult plant?
The hypocotyl is the stem of the seedling that develops below the in the plant embryo. Upon germination, the hypocotyl pushes the cotyledons above ground to develop.
What is the difference between epigeal and hypogeal germination?
in epigeal germination the cotyledon is pushed above the ground,the hypcotyle is long and the epicotyle is short whereas in hypogeal germination the cotyledon stays below the soil, epicotyle is long and hypocotyle is short.
What is the function hypocotyl?
The hypocotyl is the lower part of the embryonic stem of a plant. Its primary functions include supporting the cotyledons (seed leaves) and transporting food and water between the roots and the cotyledons. Additionally, the hypocotyl aids in the emergence of the plant from the soil during germination.
What is epigeal and hypogeal germination?
Epigeal germination is when the cotyledons emerge above the soil surface during seed germination. Hypogeal germination is when the cotyledons remain below the soil surface during seed germination.
What is the type of dicot seed germination in which hypocotyl of the embryo elongates raising the plumule and cotyledons above the soil surface?
Hypogeal germination is the type of dicot seed germination in which hypocotyl of the embryo elongates raising the plumule and cotyledons above the soil surface.

Do sunflowers undergo epigeal germination?
I'm no expert, but I believe yes: From: http://www.answers.com/topic/epigeal In botany, a seed is described as epigeal when the cotyledons of the germinating seed expand, throw off the seed shell and become photosynthetic above the ground. The converse, where the cotyledons remain non-photosynthetic, inside the seed shell, and below ground, is hypogeal. And http://www.answers.com/topic/cotyledon Cotyledons may be either epigeal, expanding on the germination of the seed, throwing off the seed shell and become photosynthetic above the ground; or hypogeal, not expanding, remaining below ground and not becoming photosynthetic. The latter is typically the case where the cotyledons act as a storage organ, as in many nuts and acorns. And http://www.answers.com/topic/germination

What is the process of germination plant growth seed formation and scattering?
Germination is the process whereby growth emerges from a period of dormancy. The most common example of germination is the sprouting of a seedling from a seed of an angiosperm or gymnosperm. However, the growth of a sporeling from a spore, for example the growth of hyphae from fungal spores, is also germination. In a more general sense, germination can imply anything expanding into greater being from a small existence or germ.

What signals the end of Germination?
When the plant stem is above ground
What is the purpose of a cotyledon to a plant?
In dicots, the cotyledon stores nutrients within a seed. Also, in some dicots the cotyledons will emerge above ground when the stem breaches the surface; when it does so the light stimulates it to grow upward. The epicotyl spreads leaves, with the cotyledon subsequently shriveling as it is no longer necessary.
What advantages would there be for all the cicadas of a brood to emerge above ground at the same time?
Some will die and some wll not
