Open in App
Solution
Hypogeal germination
During hypogeal germination, the epicotyl elongates and the plumule emerges out of the soil. The cotyledons remain underground or just above the surface. They do not turn green and eventually dry up and fall off. Examples include Cycas.
Epigeal germination
During epigeal germination the hypocotyl elongates and pushes the cotyledons out of the soil. The cotyledons become green and prepare food for the growing stem for sometime, after which they gradually dry up and fall off. It is seen in the seeds of Pinus.
Final answer
c. Hypogeal and epigeal respectively.
