The yolk sac supplies food to the developing embryo through nutrients stored in the yolk. It helps sustain the embryo's growth and development until it is ready to hatch.
yolk
The seed structure that stores food for the embryo is called the endosperm. It provides essential nutrients for the developing plant embryo to germinate and grow.
exosperm
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.
The placenta is the part of the amniotic egg that supplies food to the developing animal. The yolk provides it with food, and the albumin supplies water and nutrients.The Yolk. Yolk is a sac that is attached to the embryo that supplies food.
The developing embryo is nourished by the yolk sack until implantation. Upon implantation the placenta begins to develop, the placenta acts as the fetal lung , it transports oxygen to the fetus and carbon dioxide away from the fetus via the umbilical cord. The placenta also provides stored carbs for the developing fetus.
yolk
A seed leaf that stores food for the embryo is called a cotyledon. Cotyledons are part of the seed that provide nutrients to the developing plant embryo until it can sustain itself through photosynthesis.
The yolk sac in the developing embryo supplies nutrients and oxygen from the egg yolk. It also helps in waste removal and provides essential proteins and fats for growth and development.
endosperm
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.
