Distinguish between epigeal and hypogeal germination, with one example of each.
Original Khojo Papers practice question — not from a past board paper.
Answer
In epigeal germination the hypocotyl elongates and pushes the cotyledons above the ground, where they turn green, as in the bean. In hypogeal germination the epicotyl elongates and the cotyledons stay below the ground, as in the gram or the maize grain.
No citable source has been recorded for this record. Treat it as practice material, not as fact.
Explanation
The part of the axis that elongates is what decides which happens.
