embryot

Embryot is a term occasionally found in historical or specialized botanical and embryological texts. It refers to an early embryonic stage, typically describing an immature or primitive embryo within the ovule or seed before the differentiation of major tissues and organs. In this sense, embryot is sometimes used as a synonym for the proembryo or for the earliest cellular organization that will develop into the mature embryo.

Usage and scope of the term are limited and not standardized. Contemporary plant developmental biology generally favors more precise terms such as zygote, proembryo, globular embryo, and mature embryo. As a result, embryot is encountered mainly in older literature, glossaries, or context-specific discussions where a distinction between an initial embryonic stage and a more differentiated embryo is being emphasized.

Morphology and development described under the concept of embryot typically involve a small cluster of dividing cells with limited organization. This stage precedes the formation of recognizable embryonic axes and organs and then progresses through subsequent developmental stages to yield the fully differentiated embryo.

Taxonomic relevance is minimal beyond its descriptive role in plant development. Embryot is not a formal taxonomic category and is not widely used in modern plant anatomy or taxonomy texts.
