In dicots the fully developed embryo appears-------

In dicots, the development of the embryo (embryogeny) passes through several distinct stages. The zygote first divides to form a proembryo, which subsequently develops into a globular, then a heart-shaped (cordate), and finally a mature embryo.

In a typical dicot plant (such as Capsella), as the embryo matures, the cotyledons elongate and curve due to the spatial constraints within the ovule, giving the fully developed mature embryo a characteristic horse-shoe shape.

Answer: Horse-shoe shaped
