Just before hatching begins, the air cell expands to approximately 30% of the internal volume of the egg. As hatching begins, the beak of the embryo penetrates the inner shell membrane where it forms the inner wall of the air cell. The lungs begin to function, inhaling the air from the air cell.

What is the function of basal cell and terminal cell in plant embryo development?
terminal cell : provide polarity to the embryo and embryo develops here.. (apical cell) basal cell : develops suspensor which anchors embryo to the endosperm and serve as a nutrient producer.
Is stem cell research still cloning?
Cloning is asexual reproduction. There are all kinds of research that can be done on stem cells without creating any actual embryo or causing the gestation of an embryo in order to give birth to a new organism.
Why it is important for animals to reproduce sexually?
For external reproduction, plants that live in moist environments, need water to transport their gametes to enable sperm and egg cells to meet. For internal fertilization, the water holds enough nutrients to support and hold the embryo in the female.
What is the function of the ANS?
The purpose is to provide nourishment to a developing embryo in the seed.
What is the purpose of the 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.
What normally happens after fertilization in sexual reproduction?
After fertilization in sexual reproduction the zygote is formed. The zygote later on develops in to an embryo by embryo-genesis.
What is the purpose off the egg white in a chicken egg?

What does egg white provide for an embryo?
The albumen (egg white) consists of about 10% protein dissolved in water. The albumens primary purpose is to protect the egg yolk and provide additional nutrition for the growth of the embryo, as it is rich in proteins, though it contains almost no fat. It also helps lubricate the growing embryo to allow for movement within the shell just prior to hatch.
Where does the endosperm come from in a plant and what is its purpose?
the endosperm is in the gymnosperm 'naked seeds' and the angiosperm flowering plants. in gymno - haploid (n) gives nutrients to the embryo the only difference with the angiosperm is that its not haploid (n) but triploid (3n)
What happens in the reproduction of the embryo on day one?
The cell begins Meiosis or cell division.
What are the three purposes that a placenta serves for an embryo?
reproduction, gets rid of waste and nurishes
