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.
True.
That depends on what animal because baby chickens feed on the yolk inside the egg while a human embryos get food and oxygen from their mother's umbilical cord.
The endosperm contains the stored food that provides energy for the plant. This allows it to begin to grow into a plant.
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.
