Question

differentiate between epigeal and hypogeal germination

Answer 1

Hii...there is your answer..
In hypogeal germination, the cotyledons emerge from the seed containing enough nutrients to fuel seed development and are not photosynthetic. These seeds are usually larger than epigeal seeds. As the seedling grows, its shoot rises above ground level, while the cotyledons remain below or at ground level.

In epigeal germination, the cotyledons emerge and rise above ground level as the seedling grows. They may also serve a photosynthetic role in seedling development. Seedlings that develop this way quickly form a shoot and leaves, both of which perform photosynthesis to fuel further development.

$\orange\bigstar$ 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.
