Differbetween
In epigeous germination, the radicle emerges from the seed and the hypocotyl (the embryonic stem) elongates, raising the cotyledons, epicotyl, and remains of the seed coat aboveground. The cotyledons may then expand and function photosynthetically as normal leaves (e.g., castor bean).

What is the difference between Epicotyl and hypocotyl?
The difference between the hypocotyl and epicotyl is explained below. The part of the embryonal axis which exists below the cotyledon in a dicot embryo is called the hypocotyl. The part of the embryonal axis which exists above the cotyledon in a dicot embryo is known as the called epicotyl.
What is Epicotyl germination?
It is the region of a seedling stem above the stalks of the seed leaves of an embryo plant. It grows rapidly, showing hypogeal germination, and extends the stem above the soil surface. ... In plant physiology, the epicotyl is the embryonic shoot above the cotyledons.
What is hypocotyl germination?
The hypocotyl (short for "hypocotyledonous stem", meaning "below seed leaf") is the stem of a germinating seedling, found below the cotyledons (seed leaves) and above the radicle (root).
What is the difference between Epicotyl and Plumule?
The key difference between epicotyl and plumule is that epicotyl is the part of the embryonic axis which lies above the point of attachment of cotyledons while plumule is the tip of the epicotyl which gives rise to the shoot of the new plant. The seed is the ripened ovule which contains the embryo.
What is the function of hypocotyl?
The part of a plant embryo or seedling that lies between the radicle and the cotyledons. Upon germination, the hypocotyl pushes the cotyledons above the ground to develop. It eventually becomes part of the plant stem. Most seed-bearing plants have hypocotyls, but the grasses have different, specialized structures.
Do monocots have hypocotyl?
Monocots, such as corn (right), have one cotyledon, called the scutellum; it channels nutrition to the growing embryo. Both monocot and dicot embryos have a plumule that forms the leaves, a hypocotyl that forms the stem, and a radicle that forms the root.
What are the examples of Hypogeal germination?
In peas and corn (maize) the cotyledons (seed leaves) remain underground (e.g., hypogeal germination), while in other species (beans, sunflowers, etc.)
Is tomato Epigeal or Hypogeal?
The first leaves to develop, the cotyledons, derive from the seed and may emerge from the testa while still in the soil, as in peach and broad bean (hypogeal germination), or be carried with the testa into the air, where the cotyledons then expand (epigeal germination), e.g. in tomatoes and cherry.
What is the difference between Hypogeal and Epigeal germination?
Note: Epigeal germination could be a kind of germination whereby the seed leaves or the cotyledons are brought on to the surface or above the soil while the shoot during germination. Hypogeal germination is a form of germination whereby the seed leaves or the cotyledons remain below the soil surface during 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 ...
What are the types of germination?
The three main types are: (1) Hypogeal Germination (2) Epigeal Germination and (3) Vivipary (Viviparous Germination).
What is difference between seedling and germination?
Germination is usually the growth of a plant contained within a seed; it results in the formation of the seedling. It is also the process of reactivation of metabolic machinery of the seed resulting in the emergence of radicle and plumule.
