It is because of the make up of the membrane. Most of the bilayer is hydrophobic; therefore water or water-soluble molecules do not pass through easily. Other do pass through easily.
A cell controls what moves through the membrane by means of membrane proteins embedded in the phospholipid bilayer.
What else can I help you with?
Selective permeability refers to the fact that the plasma membrane keeps all molecules out of the cell?
Selective permeability refers to the property of the plasma membrane to allow certain substances to pass through while restricting others. This enables the cell to maintain an internal environment conducive to its function. The plasma membrane achieves selective permeability through various mechanisms such as protein channels and transporters.
What is the feature of plasma membrane that keep some substances out?
Selective Permeability
Functions of plasma memberane?
Plasma membrane permits the entry and exit of some materials in the cells. Therefore, the plasma membrane is called a selective permeable membrane. Functions of plasma membrane : 1) Diffusion 2) Osmosis 3) Mediated transport
What are the specializations of the plasma membrane?
The plasma membrane specializes in controlling the movement of substances in and out of the cell through selective permeability. It also plays a role in cell communication and recognition through protein receptors embedded in the membrane. Additionally, the plasma membrane helps maintain the cell's shape and structure.
Is homeostasis the quality of a plasma membrane that allows oxygen and glucose to move in?
Homeostasis refers to the maintenance of a stable internal environment in an organism. The permeability of the plasma membrane allows for the selective movement of substances like oxygen and glucose into cells to help maintain homeostasis by regulating internal conditions.
What part of the cell is a selective permeable membrane?
The phospholipid bilayer. plasma membrane
What is the feature of plasma membrane that keep some substances out?
Selective Permeability
What feature of the plasma membrane that keeps some substances out?
Selective Permeability
What is a selective barrier that regulats the passage of material into and out of the cell?
The plasma membrane

What is the bacterial structure that acts as a selective barrier allowing nutrients to enter the cell and wastes to leave the cell.?
plasma membrane
This structure is the outermost boundary of the cell and is semipermeable?
The structure you are referring to is the cell membrane, also known as the plasma membrane. It surrounds the cell, acts as a barrier, and regulates the passage of substances in and out of the cell through selective permeability.
Is the plasma membrane of a cell selectively permeable?
Yes, it is selective about the compounds and molecules it allows across the membrane.
What is selective ability?
Having selective ability means a person is very good at something and not that good at other things. Plasma membrane in our cells have selective ability.Synthetic membranes with selective ability have also been engineered.
What are the specializations of the plasma membrane?
The plasma membrane specializes in controlling the movement of substances in and out of the cell through selective permeability. It also plays a role in cell communication and recognition through protein receptors embedded in the membrane. Additionally, the plasma membrane helps maintain the cell's shape and structure.
What componenet of the plasma membrane forms most of the cell's outer boundary?
The human cell has three principal parts which are the plasma membrane, cytoplasm, and the nucleus. The outer boundary is the plasma membrane.
