What is the difference between hypogeal and epigeal emergence?

In hypogeal emergence the cotyledons remain below the soil surface during seedling development, while in epigeal emergence the cotyledons extend above the soil surface due to elongation of the hypocotyl. Here we examine the effect of seed size, and emergence type, on seedling growth.

What is epigeal germination and hypogeal germination give with example?

Question 7

Epigeal Germination	Hypogeal Germination
The plumule remains enclosed and protected by cotyledons till it comes out of the soil.	There is no such provision
The cotyledons become green and function as the first leaves of the seedling.	The cotyledons do not take part in photosynthesis.

How do you distinguish between hypogeal germination and epigeal germination What is the role of cotyledon S and the endosperm in the germination of seeds?

Hypogeal Seed Germination Rapid growth and elongation of epicotyls. Cotyledons remain inside the soil. Seed cotyledons emerge above the soil level/ Cotyledons become green and photosynthetic e.g.,maize, rice. Role of Cotyledons and Endosperm Cotyledons and endosperm contain reserved food materials.

Which grows faster hypogeal or epigeal?

After the faster first phase, the plant develops more slowly than plants that show hypogeal germination. It is possible that within the same genus one species shows epigeal germination while another species shows hypogeal germination.

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 meant by hypogeal germination?

Hypogeal germination (from Ancient Greek ὑπόγειος [hupógeios] ‘below ground’, from ὑπό [hupó] ‘below’ and γῆ [gê] ‘earth, ground’) is a botanical term indicating that the germination of a plant takes place below the ground. An example of a plant with hypogeal germination is the pea (Pisum sativum).

How does epigeal germination occur?

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 is epigeal germination and types?

1. Epigeal germination: Seed germination in dicots in which the cotyledons come above the soil surface. In this type, the hypocotyl elongates and raises the cotyledons above the ground surface, it is called as epigeous or epigeal germination.

What is epigeal germination examples?

What is hypogeal seed germination?

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. Normally, the cotyledon is fleshy, and contains many nutrients that are used for germination.

What is hypogeal germination with example?

In hypogeal germination, the cotyledons stay underground. But, in epigeal germination, the hypocotyls first come above the soil surface and then straightens. Examples of hypogeal germination are gram, pea, etc. Examples of epigeal germination are groundnut, bean, etc.

What is epigeal germination give two example?

Epigeal Germination:	Hypogeal Germination:
In this type of seed germination, the cotyledons come out of the soil, e.g., Castor.	The cotyledons remain inside the soil (e.g. Pea).

What is epigeal germination and hypogeal germination?

Epigeal germination is a type of germination whereby the seed leaves or the cotyledons are brought on to the surface or above the soil along with the shoot during germination. Hypogeal germination is a type of germination whereby the seed leaves or the cotyledons remain below the soil surface during germination.

What happens to the cotyledon during hypogeal germination of seeds?

During hypogeal germination of seeds, the cotyledons remain below the soil surface. This is due to the rapid development and elongation of the epicotyl. The epicotyl initially develops, and then it elongates, followed by curling up and attaining a curved structure.

What is an example of an epigeal seed?

Examples for epigeal seed germination are plumule albuminous seeds (onion), dicotyledonous albuminous seeds (castor), monocotyledonous exalbuminous seeds (Alisma) and dicotyledonous exalbuminous seeds (bean).

What are the methods of seed germination?

There are two main methods in which seed germination takes place which are, epigeal germination and hypogeal germination. These depend on the cotyledon position in the initial development process. In epigeal germination, the cotyledons are brought above the soil surface whereas in hypogeal germination the cotyledons remain in the soil.
