How many layers in a plasma layer?
The answer you're looking for is probably two, because a membrane consists of two layers of phospholipids, but it really depends on how the word "layer" is defined in this context.
What substance cannot pass directly through the phospholipids of the plasma membrane?
Many different things cannot pass through, including sugars, salts and proteins. However, oxygen, water and carbon dioxide can simply diffuse across the membrane.
How many layers is the cell membrane and what is it made of?
2 layers of lipids.
Many functions of the plasma membrane are carried out by?
Most of the active functions of plasma membranes are carried out by proteins.
What is the composition and function of each structure of the plasma membrane?
it is mostly water with many dissolved solute such as: nutrient, gases, hormones and wastes. Most plasma protein are produced by the liver. Albumin which is 60% of plasma protein serves as blood buffer to plasma osmotic pressure( the pressure that helps to keep water in the bloodstream). Another function of is plasma distribute heat.
How many membranes does plasma membrane have?

How many layers does the plasma membrane has?
Two phospholipid layers? I think.
What is the chemical formula for phospholipids?
Phospholipids are a type of lipids that can make up two layers of lipid molecules, which called polar membrane. It also called lipid bi-layers. This is the main role of phospholipids in living organism.
What prevents charged molecules from diffusing across the cell membrane?
This depends on the membrane. For example, the plasma membrane of a eukaryotic cell allows many ions to passively diffuse. However, the prevention of ions across a membrane indicates that the membrane in question is most likely non-polar, meaning that they are hydrophobic. Non-polar molecules do not like to mix with polar molecules like ions, therefore they repel one another and active diffusion must be used to transport ions across a non-polar membrane.
What is the primary molecule of the cell membrane?
membrane lipid which is made up of phospholipids and glycolipids. both phospholipids and glycolipids makes up glycerolipid.
What is the principle of the fluid mosaic model of cell membrane structure?
The plasma membrane is described to be fluid because of its hydrophobic integral components such as lipids and membrane proteins that move laterally or sideways throughout the membrane. That means the membrane is not solid, but more like a 'fluid'. The membrane is depicted as mosaic because like a mosaic that is made up of many different parts the plasma membrane is composed of different kinds of macromolecules, such as integral proteins, peripheral proteins, glycoproteins, phospholipids, glycolipids, and in some cases cholesterol, lipoproteins.
How many membranes are around the plasma membrane?
The plasma membrane is a bi-layer, so two.
What is the cell membrane's composed of?
composed of a phospholipid bilayer, which has 2 layers of phospholipids back-to-back
Chemicals that move in and out of cells by diffusion?
The cell cotains phospholipids ,proteins , and carbohydrates. Carbohydrates can be attached to either the phospholipids or the proteins in the cell membrane. Sometimes carbohydrates (sugars) are attached to cell membrane phospholipids and to cell membrane proteins
Which of the following statements about a typical plasma membrane is correct?
The Correct Answer: The sides of the plasma membrane that face the cytoplasm and the outside of the cell have different lipid and protein composition.
What substance cannot pass directly through the phospholipids of the plasma membrane?
Many different things cannot pass through, including sugars, salts and proteins. However, oxygen, water and carbon dioxide can simply diffuse across the membrane.
