examples of epigeal germination
- common example is bean.
- phaseolus
- Lilium
Answer:
For example, bean.
Explanation:
The bean seed absorbs water through the micropyle and becomes turgid resulting in breaking of the testa.
The bean seed absorbs water through the micropyle and becomes turgid resulting in breaking of the testa.The radical emerges out and grows downwards to form the roots system.
The bean seed absorbs water through the micropyle and becomes turgid resulting in breaking of the testa.The radical emerges out and grows downwards to form the roots system.The arched hypocotyl grows straight upward making the cotyledons emerge out of the soil thus making it an epigeal type of
For example, the initial elongating region of the seedling shoot axis in garden bean (Phaseolus), castor bean (Ricinus), and onion (Allium) is the hypocotyl, located below the cotyledonary node.Thus, when the hypocotyl elongates it lifts the cotyledon(s) above the soil.

In most epigeal seedlings both the hypocotyl and epicotyl elongate. In contrast, only the epicotyl elongates in hypogeal seedlings, such as in pea (Pisum).

In contrast, only the epicotyl elongates in hypogeal seedlings, such as in pea (Pisum).The seeds of members of the grass family are also hypogeal. For example, in maize (Zea) the axis directly above the modified cotyledon, or scutellum, is called the mesocotyl.
