Explanation:

Dicotyledonous plants are those that have two cotyledons or seed leaves. These cotyledons can be seen in the seed, which is the embryonic plant enclosed in a protective coat. The embryo of a typical dicotyledonous plant has several parts, including the epicotyl, hypocotyl, and embryonal axis. However, it does not have an epiblast.

Embryo Parts:

1. Epicotyl: This is the upper part of the embryonal axis that lies above the cotyledons. It includes the shoot apex and the first few leaves.

2. Hypocotyl: This is the lower part of the embryonal axis that lies below the cotyledons. It connects the cotyledons to the radicle, which is the embryonic root.

3. Embryonal Axis: This is the central axis of the embryo that includes both the epicotyl and hypocotyl. It is the primary axis of growth for the plant.

4. Epiblast: This term is not used to describe any part of the dicotyledonous embryo. It is a term used in embryology to describe a layer of cells in the embryo that gives rise to the ectoderm and endoderm.

Conclusion:

In conclusion, a typical dicotyledonous embryo does not have an epiblast. It has several other parts, including the epicotyl, hypocotyl, and embryonal axis, which are important for the growth and development of the plant.

Epiblast is present in embryo of monocot seeds.
