examples of hypogeal germination is mango and epigeal is bean
Do sunflower undertake epigeal germination
name few seeds that undergo epigeal growth
Presumably you are talking about epigeal development, where the cotyledons grow out from the seed. At first they absorb water, and food from the adjacent parts of the seed, then when they are above ground, many of them photosynthesise.
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.
These fungi are called mycorrhizical fungi, and many exist. I could list a few mushrooms visible to us, and non-hypogeal. (Meaning not underground) Amanita mushrooms, Boletes and Tuber.
hypogeal
in epigeal germination cotyledons and plumule comes out from soil in hypogeal germinatin only plumule comes out from soil
no it is epigeal type of germination because the cotyledons are under the soil
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.
Do sunflower undertake epigeal germination
It helps the seeds breathe in and out through the stomata.
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
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.
pea, maize, mango, green gram and bean
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.
Hypogeal germination is generally seen on monocots seeds
Epigeal germination is the process in which the seed leaves or the cotyledons are brought on to the surface along with the shoot during germination. Hypogeal germination is the process in which the seed leaves or the cotyledons remain below the soil surface during germination.
