What is a small sac that forms part of a cell membrane?
A vesicle forms as a small sac from the cell's membrane.
Which group has 4 extraembryonic membranes- aquatic animals or land animals?
Land animals have four extraembryonic membranes: amnion, chorion, allantois, and yolk sac. Aquatic animals typically have fewer extraembryonic membranes as they rely on the water environment for support and protection of their embryos.
Which group has four extraembryonic membranes aquatic animals or land animals?
The answer to this is not based on where the animal lives but on the type of animal. Animals that lay eggs have fewer extraembryonic membranes than placental mammals...there are mammals in the ocean as well as on land.
Why are extraembryonic organs called provisional?
Extraembryonic organs, such as the placenta, yolk sac, and amnion, are called provisional because they play critical roles in supporting the embryo in utero but are ultimately discarded after birth. These organs are temporary structures that facilitate the exchange of nutrients, gases, and waste between the mother and developing embryo until the fetus is born and able to sustain itself.
What is the chorionic membrane?
The chorionic membrane is a thin, outermost membrane that surrounds the fetus in the womb. It is composed of layers of cells derived from both the embryo and the mother and plays a role in the exchange of nutrients and waste between the fetus and the mother. The chorionic membrane eventually fuses with the amniotic membrane to form the amniotic sac.
What is a small sac that forms part of a cell membrane?
A vesicle forms as a small sac from the cell's membrane.
Is the membrane that forms a sac around an animal embryo.?
The membrane that forms a sac around an animal embryo is called the amniotic sac. The embryonic sac is a bag of fluid inside of a woman's womb where the unborn baby develops and grows.
What is the membrane that forms a sac around an animal embryo?
The inner most membrane is the fluid filled amniotic sac, next is the yolk sac, where the first blood cell originates. The allantois forms near the yolk sac, while the chorion surrounds all the other ones.
Which group has 4 extraembryonic membranes- aquatic animals or land animals?
Land animals have four extraembryonic membranes: amnion, chorion, allantois, and yolk sac. Aquatic animals typically have fewer extraembryonic membranes as they rely on the water environment for support and protection of their embryos.
Is a frog an amniote?
No, frogs are not amniotes. Amniotes are a group of vertebrates that possess extraembryonic membranes, such as reptiles, birds, and mammals. Frogs belong to a different group of vertebrates called amphibians, which do not have these extraembryonic membranes.
Which group has four extraembryonic membranes aquatic animals or land animals?

What is a yolk fellow?
I believe you're referring to the yolk sac. In embryology, the yolk sac is an extraembryonic membrane that provides nutrients to the developing embryo in birds, reptiles, and fish. In humans, the yolk sac serves as a source of early blood cells and contributes to the formation of the digestive tract.
Which of these membranes forms a protective sac that surruonds the embryo?
The amniotic sac is the sac in which the fetus develops in amniotes. Its wall is the amnion, the inner of the two fetal membranes. It encloses the amniotic cavity and the embryo.
What is the name for the protective structure that forms around an embryo?
Amniotic membrane or amniotic sac, containing the embryo and amniotic fluid.
What is a membrane-bounded sac?
Vacuoles
What will happen if a membrane sac filled with large molecules of oil is suspended in a beaker of water?
If a membrane-bound sac filled with large molecules of oil is suspended in a beaker of water, water will start to enter the sac. The sac will then swell.
The developing embryo is surrounded by a protective membrane called the?
amniotic sac :)
