What is germination hypogeal in?
Hypogeal germination is among the prominent types of germination in which the seed leaves or cotyledons stay under the soil surface during the entire germination process.
How does hypogeal germination occur?
Hypogeal germination implies that the cotyledons stay below the ground. The epicotyl (part of the stem above the cotyledon) grows, while the hypocotyl (part of the stem below the cotyledon) remains the same in length. In this way, the epicotyl pushes the plumule above the ground.
Where is hypogeal germination found?
– Hypogeal germination is the type where the cotyledons stay below the ground, the epicotyl above the cotyledon grows, while the hypocotyl below the cotyledon remains the same in length. – Examples of hypogeal germination include pea, mango, maize, and lily.
Which seed will show hypogeal germination?
Maize-Albuminous seed shows hypogeal germination. Maize is an albuminous seed which undergoes hypogeal germination in which the epicotyls elongates and the cotyledons remain in the soil. Hence, the correct answer is option D, Maize.
What is Epigeal germination?
Epigeal germination implies that the cotyledons are pushed above ground. The hypocotyl elongates while the epicotyl remains the same in length. Normally, the cotyledon itself contains very little nutrients in plants that show this kind of germination.
Is gram Hypogeal germination?
Hypogeal Germination: In this type of germination, the epicotyl elongates and the cotyledons remain below the soil. Pea, mango, maize, rice, gram and groundnut have germination of this kind.
Is gram hypogeal germination?
What is epigeal germination?
Which seed shows Epigeal germination?
Phaseolus: the common bean (Phaseolus vulgaris) shows epigeal germination, whereas the runner bean (Phaseolus coccineus) shows hypogeal germination.
What is epigeal and Hypogeal germination?
The germination can be of two types, depending on the positioning of the cotyledons or seed leaves: >If the cotyledons remain below the soil, it is called hypogeal germination. >If the cotyledons emerge on the surface of the soil, is called epigeal germination.
What causes epigeal germination?
Epigeal germination implies that the cotyledons are pushed above ground. The hypocotyl elongates while the epicotyl remains the same in length. In this way, the hypocotyl pushes the cotyledon upward. Plants that show epigeal germination grow relatively fast, especially in the first phase when the leaflets unfold.
What are hypogeal and epigeal?
Epigeal germination refers to the germination of a plant that takes place above the ground while hypogeal germination refers to the germination of a plant that takes place below the ground.
