Tardigrade Admin · Accepted Answer

Epiblast of monocot embryo is considered as rudimentary secondary cotyledon.
Epiblast formation is the characteristic of monocot seeds.
An important point to note here is that the endosperm present inside the seed is responsible for storing the nutrients and transferring it to the growing embryo for its nourishment.
In dicot seeds, entire endosperm gets used up by the developing embryo and most of it is utilized during the formation of two cotyledons, which are also known as embryonic leaves. Therefore, in dicots, no remnants of cotyledons are seen.
In monocot seeds on the other hand, the embryo is unable to utilize entire endosperm and formation of only one cotyledon takes place (which is the reason monocotyledonous seeds get this name) and only remnant of the second cotyledon is observed. This remnant of the second cotyledon is known as epiblast.
Therefore, it can be said that in monocot embryo, epiblast is the rudimentary cotyledon.
