blood
The mammal embryo receives its nutrients from the mother through the placenta. The placenta allows nutrients to travel from the mother's system to the embryo's, and for waste products to leave the embryo's system so they can be disposed of by the mothers.
The Placenta uses a the process of diffusion to diffuse the nutrients from the mothers blood into the babies. Then the umbilical cord carries the nutrients to the baby to the Placenta. Answer is Placenta
The endosperm does. It acts much like yolk in an egg does for the embryo developing in the egg: provides the necessary nutrients for the developing embryo to grow from.
Not in the normal sense. The developing embryo absorbs nutrients already in the egg.
Seeds provide nutrients and protection to a developing embryo when it is at its most fragile.
its gets it all through the umbilical cord
The endosperm provides nutrients for the developing plant embryo. It primarily stores carbohydrates, proteins, and fats to support the growth and development of the embryo until it can photosynthesize and produce its own food.
The technique of embryo splitting involves removing an embryo. Individual cells from this embryo are removed and then placed into petri dishes that contain the correct nutrients and hormones for growth. Each of the removed cells now divides to form a new embryo. These embryos are then implanted into the uterus of surrogate mothers. These surrogate mothers will then give birth to identical young.
It's a sack and not an egg but the primary food source, the only one, is the placenta and the nutrients go via the umbilical cord.
embryo
The common term is pregnancy. The technical term is gestation.
The egg yolk is the main source of food for a developing embryo, and the albumin (egg white) supplies other nutrients as well as water to prevent the embryo from drying out.
