Does epigeal germination occur in Dicots?
correct. Most eudicots do show epigeal germination.
What are examples of epigeal germination?
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 …
Which Monocot shows epigeal germination?
Some genera in which this happens are: Phaseolus: the common bean (Phaseolus vulgaris) shows epigeal germination, whereas the runner bean (Phaseolus coccineus) shows hypogeal germination.
Which seed is epigeal germination?
Epigeal Germination: In seeds with epigeal germination, the cotyledons are brought above the soil due to elongation of the hypocotyl. In castor, cotton, papay, onion (Figs. 4.7., 4.8), flat green leaf like cotyledons can be seen in the young seedlings.
Does gram show epigeal germination?
Assertion: Gram, pea and mango show epigeal germination. Reason: In epigeal germination, after radicle hypocotyl grows faster.
Does pea show epigeal germination?
In epigeal germination, the cotyledons are pushed above the ground and then germination takes place above the ground. Hypogeal germination can be seen in plants like coconuts, pea, maize, etc whereas the epigeal are seen in bean or caster plants.
Is green gram epigeal or hypogeal?
Mostly, the monocot seeds are the ones that show hypogeal germination prominently. Hypogeal germination occurs in several plants, including maize, arum, water lily, gram, pea, and coconut.
What is hypogeal germination give example?
An example of a plant with hypogeal germination is the pea (Pisum sativum). The opposite of hypogeal is epigeal (above-ground germination).
Which seed show hypogeal germination?
Does maize 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 happens in epigeal germination?
In epigeal germination, the cotyledons are pushed above the ground and then germination takes place above the ground. The cotyledons are pushed upwards due to the elongation hypocotyl. The hypocotyl lies between the radicle and cotyledons. In this germination, the cotyledon germinates below the ground.
What comes out first in epigeal germination?
angiosperm seed germination In epigeous germination, the radicle emerges from the seed and the hypocotyl elongates, raising the cotyledons, epicotyl, and remains of the seed coat aboveground.
What is epigeal germination?
Epigeal germination is a process of germination in which the cotyledons emerge out of the soil due to the elongation action of the hypocotyl. The hypocotyl is generally the part of the stem of an embryo plant beneath the stalks of the seed leaves or cotyledons and directly above the root.
What is the function of the hypocotyl In epigeal germination?
In Epigeal germination, the terminal part of the hypocotyl is curved to protect the plumule from the friction of the soil. The cotyledons in Epigeal germination are brought out of the soil by the excessive growth of the hypocotyl.
What is the difference between epigeal and hypogeal seeds?
Generally dicot seeds show this type of germination (Epigeal). Generally monocot seeds show hypogeal germination. Epigeal germination occurs in beans, Alisma, onion and, papaya, castor. Hypogeal germination occurs in coconut, pea, gram, water lily, arum and maize.
What is epicotyl in plants?
Epicotyl is short in plants that show Epigeal germination. The cotyledons turn green, act as the first leaves of the plant and take part in photosynthesis. The plumule remains enclosed and protected by cotyledons till it comes out of the soil. Generally dicot seeds show this type of germination (Epigeal).
