Question

Differentiate between epigeal and hypogeal germination❤❤❤❤❤​

Answer 1

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) stays the same length. In this way, the epicotyl pushes the plumule above the ground.

The main difference between epigeal and hypogeal germination is that inepigeal germination, the cotyledons emerge out of the soil duringgermination whereas, in hypogeal germination, the cotyledons remain inside the soil. ... The embryo penetrating the seed coat is the conclusion of the germinationprocess.

$\orange\bigstar$ Ephigeal germination :-

• The cotlyledons comes out of the soil.

• The cotlyledons becomes flat, green leaf like.

• While coming out, hypocotyl develops curvature.

• eg - Tamarind, Castor, Cucumber, etc.

$\orange\bigstar$ hypogeal germination :-

• The cotlyledons remains in the soil.

• Cotlyledons remains enclosed within the seed.

• Epicotyl develops curvature.

• eg - Gram, Pea, Maize.
