What is the main difference between epigeal and hypogeal germination?
Write the difference between epigeal and hypogeal germination.
Epigeal Germination | Hypogeal Germination |
---|---|
Epicotyl is short | Epicotyl is long |
The cotyledons turn green and perform photosynthesis | The cotyledons have no role in photosynthesis |
It is generally shown by the dicot seeds | It is generally shown by the monocot seeds |
What grows faster hypogeal germination?
A hypogeal germination is a form of seed germination that occurs mainly for both monocot and dicot seeds. The cotyledons stay inside the soil due to quicker growth and development in the epicotyl’s length.
What is the advantage of hypogeal germination?
The advantage of hypogeal germination is that the plant or the seedlings are protected from early grazing and the drawback or the disadvantages of hypogeal germination is that the plant cannot begin to synthesize its own food or photosynthesize until the true leaves have completely appeared.
Which elongates faster in epigeal germination?
The portion of the embryonal axis which lies above the cotyledon in a dicot embryo is known as the epicotyl. Hypocotyl elongates faster than epicotyl in epigeal germination that is seen in bean, papaya, and cucumber. Thus the correct answer is option D.
What is epigeal germination give two examples?
Epigeal and hypogeal are two types of germination in which epigeal is germination that brings cotyledons out of the soil surface, one example of plants that experience epigeal germination is green beans, while hypogeal is germination which perpetuates cotyledons in the soil, one example of plants that have germination …
What is epigeal germination?
Epigeal germination (Ancient Greek ἐπίγαιος [epígaios] ‘above ground’, from ἐπί [epí] ‘on’ and γῆ [gê] ‘earth, ground’) is a botanical term indicating that the germination of a plant takes place above the ground. An example of a plant with epigeal germination is the common bean (Phaseolus vulgaris).
What crops show epigeal germination?
– Epigeal germination is the type where the cotyledons are above the soil surface as the hypocotyl elongates very rapidly. The epicotyl remains unchanged in length. – Examples of epigeal germination are cotton, sunflower, castor, and bean (or common bean).
Is String bean epigeal or hypogeal?
What do you mean epigeal growth?
What is the meaning epigeal?
Definition of epigeal 1 of a cotyledon : forced above ground by elongation of the hypocotyl. 2 : marked by the production of epigeal cotyledons epigeal germination. 3 : living on or near the surface of the ground also : relating to or being the environment near the surface of the ground.
Is green gram epigeal or hypogeal?
The correct answer is Epigeal. Mung beans are part of the Fabaceae plant family, which means the seeds of this plant come from pods. Mung beans typically germinate within four to five days.
Is rice an epigeal?
Figure 2: Epigeal and Hypogeal Germination All monocotyledons such as maize, rice, wheat, and coconut show hypogeal germination. However, some dicotyledons such as groundnut, gram and pea show hypogeal germination.
