What Component of cell membrane that makes it impermeable to water?

The cell membrane is not impermeable to water but semi permeable which means it allowa only water to enter into the cell when the concentration of water molecules is higher in the fluid surrounding the cell than the fluid inside the cell.

A cell membrane is relatively impermeable to substances that are?
water-soluble molecules such as amino acids, sugars, protiens, nucleic acids, and various ions
Is a raincoat permeable or impermeable?
A raincoat is impermeable because it is made with fabric or plastic that is made to repel water.
What is an osmotically active substance?
It is a solute that causes osmosis to occur. For instance, if a solution contains sucrose and the membrane is impermeable to sucrose,, water will move out of the cell and into the solution to dilute it. Hence the solution is hypertonic. Sucrose would be considered an osmotically active solution in this case because it induces osmosis of water across a membrane.
What makes up protoplasm?
Cell surface membrane, cytoplasm, and nucleus.
What makes up most of the molecules in the plasma membrane?
The main component of the cell membrane is phospholipids. These are molecules with a polar (hydrophilic, water-loving) head composed of a phosphate (and usually a choline) and a non-polar (hydrophobic, water-hating) tail composed of fatty acids. In the cell membrane, these phospholipids are arranged in a bilayer - with heads facing the outside and the tails facing each other in the centre of the membrane.
Do the hydrophobic tails of plasma membrane promote osmosis?
No.Hydrophobic tails avoid water and line up in the center of the membrane and makes the plasma membrane impermeable to most water-soluble molecules.
Definition of impormable membrane?
I impermeable membranes I think are these which dont allow the entry of even the solvent molecules and that kinna example can be seen in the plants. The cells with suberin and lignin covering act as impermeable membrane and do not allow water molecules to tranport through it. by:deathkiddah ^^
What membrane structural component is involved when water is entering the cell?
Osmosis

Which layers are impermeable?
Impermeable means that stuff can't go through it. Wax is impermeable to water. Paper towels are not. Glass is impermeable to air. Mesh cloth is not. Some things are impermeable to one thing but not another. Clear plastic is impermeable to water and air, but not light. Lead metal is impermeable to x-rays, but not heat. Which layer is impermeable depends on what it is impermeable to.

Is the water table below the layer of impermeable rock?
No, impermeable rock is the layer of rock that water CAN'T pass.
Is a raincoat permeable or impermeable?
A raincoat is impermeable because it is made with fabric or plastic that is made to repel water.
Which component makes up 90 percent of the blood?
Water.
When a soil is impermeable?
The water stays there and forms a water table, like when you dig down in sand and reach water.
What are permeable and impermeable rocks?
Permeability is a measure of how well a porous media transmits a fluid. It has nothing to do with the fluid itself. It is measure in (length)2. The Hydraulic Conductivity is a measure of how easily water moves through the porous media. It depends on the permeability of the matrix, but also is a function of the fluid. It is a measure of (length)/(time)
Is an aquitard porous or impermeable?
it has to be impermeable so it can line the aquifer without letting water straight through
