Embryo

The point at which an embryo becomes a fetus has apparently been chosen arbitrarily.

A developing embryo connects to the placenta via the umbilical cord.

When a coral egg and sperm join together as an embryo, they develop into a coral larva, called a planula. Planulae float in the ocean, some for days and some for weeks, before dropping to the ocean floor. Then, depending on seafloor conditions, the planulae may attach to the substrate and grow into a new coral colony at the slow rate of about .4 inches a year.

This is a human embryo.

Morphogenesis is the development, from the embryo, of the characteristic forms and structures of a species.

Two cells (a sperm and an egg) come together to form a new cell (the embryo), which replicates by division in geometric progression to form a human being, which has about 37 trillion cells.

The egg is a symbol of fertility and can be considered the primordial seed, the first embryo that emerged from the chaos to generate everything that exists.

In the evening, I returned to Tim Hortons to eat what was becoming my usual: two hash browns and an oat milk iced coffee. I should, maybe, go back to croissants, sometime. There were Sinospheric customers. There was a robust East Indian customer in a corner. One South Asian vendor commented, "Viktor is still like an embryo!" At home, I listened to a radio app on my tablet: Zouk Hits, Southeast Asia Psychedelics, Baroque, etc. It was the 27th of December of 2024.

The albumen of an egg surrounds the yolk and provides nutrition for the developing embryo.

SE onset depends on a complex network of interactions among plant growth regulators, mainly auxins and cytokinins, during the proembryogenic early stages, and ethylene and gibberellic and abscisic acids later in the development of somatic embryos.
