Amnion
A vesicle forms as a small sac from the cell's membrane.
The chorionic membrane is the outer sac which surrounds the developing fetus
A membranous sac is, as it says, a sac with a membrane. What it is specifically varies. Bronchi in the lungs are membranous sacs and the amniotic sac on a baby is membranous.
chorion
The membrane bound sac formed from the smooth endoplasmic reticulum is called the cisterna. It refers to the part of the ER that is studded with ribosomes.
A vesicle forms as a small sac from the cell's membrane.
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.
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.
Vacuoles
Amniotic membrane or amniotic sac, containing the embryo and amniotic fluid.
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 chorionic membrane is the outer sac which surrounds the developing fetus
A sac bounded by a single membrane is called a lysosome. This organelle is present only in animal cells and contributes in intracellular digestion.
