Plasma membrane is made of two layer of phospholipids. The outer layer is hydrophilic while inside the membrane is hydrophobic therefore plasma membrane is not a hydrophobic barrier -it regulates what enters and leave the cell.

Wiki User
∙ 13y agoNo, as the head is not hydrophobic, it is actually hydrophilic.
However, the tail is hydrophobic.
Wiki User
∙ 11y agoThe part with the phosphoate residues, known as the head group, is hydrophilic.

What molecules add support to plasma membrane?
The intrinsic properties of the hydrophilic/hydrophobic/hydrophilic double layer of the membrane gives it support, due to the hydrophobic effect.
What is the structure of a cell membrane in plant cells?
The cell membrane is composed of phospholipid bi-layer and proteins. The phospholipids are both hydrophillic and hydrophobic and makes the cell membrane be selectively permeable, that is allows only curtain molecules to pass through the membrane. The proteins function is to determine wchich molecules must go in and wchich shouldn't go inside the cell.
What makes up cells membrane?
The Cell Membrane is made up of a bilayer (double layer) of Phospholipids. These Phosophlipids are oriented by its hydrophobic (water fearing) tails while its head are hydrophilic (water loving).
What is the outer layer of a cell that acts as a gatekeeper to a cell?
Cell Membrane
Why are membrane proteins are not very soluble in water?
Hydrophobic amino acids on lipid bi-layer
What is the outer layer in animal cells called?
the cell membrane. It is a protein mosaic this is hydrophobic on both sides and hydrophllic in the center.
The cell membrane is made of a double layer of?
The cell membrane is semi-permeable controlling the movement of substances in and out of the cell. It contains a phospholipid bilayer consisting of hydrophobic tails and hydrophilic heads. Also contained in the cell membrane are transport proteins.
Why are amphipathic compounds important to the cell membrane?
The are the cell membrane! The are the phospholipid bi- layer of the cell membrane that has a hydrophobic tail and a hydrophillic head which allows cell membranes to form mycells that divide the interior of the cell from the exterior.
What molecules add support to plasma membrane?
The intrinsic properties of the hydrophilic/hydrophobic/hydrophilic double layer of the membrane gives it support, due to the hydrophobic effect.
Is The hydrophobic part of a cell membrane is on the inside of the phospholipid bilayer?
hydrophobic
What is the stiff outer layer that surrounds the outer layer of the cell membrane?
cell membrane
What is a selective barrier regulating the passage of materials into and out of the cell?
In a plant cell, this selective barrier is known as the cell membrane but also a plant cell has a cell wall. The cell membrane is semi permeable allowing only certain materials so the cell membrane allows in materials and the cell wall ''digests it''. While in a plant cell does not have a cell wall only a cell membrane.It is the cell membrane that acts as its selective barrier.
What force pushes the cell membrane up against the cell wall?
what force pushes a cell membrane against a cell wall

What can a cell membrane be described as a double layer of?
The basic structure of a cell membrane is the phospholipid bilayer. Both layers of phospholipids have their hydrophobic tails facing towards the centre of the bilayer, whereas the hydrophilic heads neighbour the cell surroundings and the cytoplasm itself.
What is the layer that protects a cell from its environment?
the cell membranecell membrane
