Where do the amniotic membranes come from?
Human amniotic membranes come from the fetal membranes which consist of the inner amniotic membrane made of single layer of amnion cells
What do cell membranes consist of?
Each membrane is a phospholipid bilayer with proteins embedded in it.This description applies to all membranes, the internal ones as well as the plasma membrane (the one surrounding the cytoplasm).To see an image click the link below.
State one function of the protein molecules that are located in cell membranes?
The protein molecules in the cell membrane consist of adenine, 5 carbon sugars and three phosphate groups.
Membrane pores consist of what chemically?
Protein
Does the nuclear membrane consist of two layers?
Yes, the nuclear membrane consists of two layers, just like the plasma membrane.
What contains a smooth outer and folded inner membrane in a cell?
The mitochondria are surrounded by two membranes, the outer is smooth & the inner is folded into critae which increase the surface area. :)
Plasma membranes consist of what kind of membrane?
A phospholipid bilayer.

What is a meninges?
The meninges, the singular is meninx, are the three membranes that surround and protect the brain. Just like our spinal column our brain is protected from damage by both bone, e.g. skull, and skin like membrane called the meninges.
Is the nuclear envelope composed of two bilayers?
There are two phospholipid bilayers that are present in the nuclear envelope. They are the inner and outer phospholipid bilayers. Nuclear envelope are also referred to as karyotheca, nucleolemma or nuclear membrane.
What structure in a cell is composed mostly of a Phospholipid bilayer?
Most structures consist of a phospholipid bi-layer although that term is mostly associated with the cell wall in my experience. other structures such as the rough and smooth Endoplasmic Reticulum also use phospholipid bi-layers to partian themselves from the rest of the cell.
State one function of the protein molecules that are located in cell membranes?
The protein molecules in the cell membrane consist of adenine, 5 carbon sugars and three phosphate groups.
What is the structural model of the plasma membrane called?
The plasma membrane is the most thoroughly studied of all cell membranes, and it is largely through investigations of the plasma membrane that our current concepts of membrane structure have evolved. Theplasma membranes of mammalian red blood cells (erythrocytes) have been particularly useful as a model for studies of membrane structure. Mammalian red blood cells do not contain nuclei or internal membranes, so they represent a source from which pure plasma membranes can be easily isolated for biochemical analysis. Indeed, studies of the red blood cell plasma membrane provided the first evidence that biological membranes consist of lipid bilayers. In 1925, two Dutch scientists (E. Gorter and R. Grendel) extracted the membrane lipidsfrom a known number of red blood cells, corresponding to a known surface area of plasma membrane. They then determined the surface area occupied by a monolayer of the extracted lipid spread out at an air-water interface. The surface area of the lipid monolayer turned out to be twice that occupied by the erythrocyteplasma membranes, leading to the conclusion that the membranes consisted of lipid bilayers rather than monolayers
What is photosynthetic membrane?
It consist of "photosystem".
What type of lipid molecules do membranes consist of?
Phopholipids - They have a hydrophillic head that is positioned to the inside of the cell and the outside environment. They also have hydrophobic tails that point towards each other inside the membrane. This is why cell membranes are referred to as lipid bilayers. They are 2 layers of phospholipids organzied by their interaction with water.
Membranes are organs formed by the combination of which tissues?
they consist of lipids and proteins
