the embryo is killed
On the gametophyte, cells in the archegonium and antheridium form the eggs and sperm. The sperm swim to the egg and fertilize it, forming the zygote. The embryo develops into the sporophyte, still attached to the gametophyte.
Plants are referred to as embryophytes because they develop from an embryo that forms after fertilization. This term highlights a key characteristic of land plants: their reproductive cycle includes a multicellular diploid phase (the sporophyte) that arises from the fertilization of gametes, leading to the formation of an embryo. Additionally, the term emphasizes their evolutionary adaptation to terrestrial environments, where the protection and nourishment of the embryo is crucial for survival.
Once stem cells are removed from the embryo, the remaining embryo cannot develop into a fetus because the stem cells are essential for its growth and differentiation. The embryo is typically discarded after the stem cell extraction process.
before birth the zygote develops first into an embryo and the into a fetus
On the gametophyte, cells in the archegonium and antheridium form the eggs and sperm. The sperm swim to the egg and fertilize it, forming the zygote. The embryo develops into the sporophyte, still attached to the gametophyte.
In pine trees, the sporophyte generation consists of the adult tree itself, including the roots, trunk, branches, and needles. The sporophyte produces reproductive structures called cones, which contain the spores that will develop into the next generation of gametophytes.

Embryo get implanted on the uterine wall.

Seeds are comprised of an embryo and an extra layer of sporophyte tissue which hardens to produce the seed coat, so in a sense, yes seeds are made up of cells because the embryo is produced by the fertilization of plant gametes to form a zygote.
The Embryo happens to be the lost Heart's Egg of Little Hikaru.
A twin is on the way
When a hen lays a fertilized egg, there is no embryo inside. Embryo's only start to form once they are incubated.
Siamese twins.
They form an embryo
That's a miscarriage.
