What is semi-permeable membrane means?

A semi- permeable membrane is a filtration membrane that is permeable to one or more contaminants, but not to all contaminants. The size and type of the pores in the membrane determines the size and species of the contaminants the membrane can filter out.

What is a semi-permeable membrane in medicine?

An example of a semi-permeable membrane is the skin. If you have ever looked at a cut on your skin, you will notice an almost clear line where the skin is separating from the deeper tissue beneath. This is the epidermis, and it is a simple example of a natural semi-permeable membrane. The skin acts as a protective barrier against germs and harmful substances that can enter the body.

What is semi-permeable membrane in molecular biology?

A semi-permeable membrane refers to a biological membrane (a cell or organelle wall) that allows some materials to pass through it while retaining the shape and size of the membrane. The membrane selectively allows passage of some substances that have the chemical properties required for passing through it. Examples of these substances are water, ions, small chemicals, and proteins.

What is semi-permeable membrane in chemistry?

A membrane is a thin layer of any natural or synthetic material that acts as a barrier and allows the passage of particular substances and components. The term “semi-permeable” refers to the permeability of a membrane. In other words, it defines the ability of the membrane to allow the flow of one substance through the membrane while stopping the flow of other substances.

What is a semi-permeable membrane in biology?

The membranes in living organisms provide a barrier between the internal and external environment. The cell membranes that surround the cell in all living things play an important role in maintaining the internal environment of the cell. They control what enters and exits the cell, thus allowing each cell to stay alive.
