An embryo plugs into it's Mothers blood supply through the placenta. The embryo gets all it's nutrition and oxgen through this connection.
what is the source of nourishment for developing fish embryos?
from where embryo get food and water?
No.
the 2 things that ALL growing embryos need are food and oxygen
No, embryos do not look for their own food outside the egg. They rely on nutrients stored in the egg or provided by the parent until they hatch.
cotyledons of the seed.
The main source of embryonic stem cells is embryos that are created in a laboratory through in vitro fertilization techniques. These embryos are usually donated for research purposes with informed consent from the donors. Embryonic stem cells are pluripotent, meaning they have the ability to differentiate into all cell types in the body.

Seeds contain embryos to provide an energy source for the plant when it starts to shoot out of its seed. Think of it like the yoke for a chicken inside an egg. The yoke is the embryo of the egg.
The endosperm contains the stored food that provides energy for the plant. This allows it to begin to grow into a plant.
All developing embryos need a source of nutrients for growth and development, as well as proper oxygen supply for metabolism. These two factors are essential to support the key processes of cell division and differentiation during embryonic development.
If the animal comes from an egg it will get its nutrients from the yolk. If it is a mammal it will get it from the umbilical cord.
