How does a sieve or colander demonstrate the property of selective permeability?
A sieve or colander demonstrates selective permeability by allowing smaller particles, like water or liquid, to pass through while blocking larger particles, like solids. This property is based on the size of the holes or pores in the sieve or colander, which determine what can pass through and what gets caught.
What is a Property of a membrane that allows some substances to move into and out of the cell?
semi- or selective permeability
Which phrase best describes the property of selective permeability large molecules pass all ions pass all molecules pass some molecules pass?
The phrase "some molecules pass" best describes the property of selective permeability.
How does a sieve demonstrate the property of selective permeability?
A sieve demonstrates selective permeability by allowing certain-sized particles to pass through while blocking larger particles. This is similar to how cell membranes selectively allow certain molecules to enter or exit the cell based on their size and charge.
What property describes the plasma membrane's ability to regulate movement of molecules into and out of the cell?
Selective permeability is the property that describes the plasma membrane's ability to regulate the movement of molecules into and out of the cell, allowing only certain substances to pass through while restricting others. This selective permeability is achieved through the presence of various proteins and lipid components in the membrane.
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 property of the cell membrane allows it to maintain cell homeostasis?
The property of selective permeability allows the cell membrane to regulate the movement of substances in and out of the cell, helping to maintain cell homeostasis by controlling the internal environment. This helps the cell to maintain the proper balance of ions, nutrients, and waste products.
What is the property of the cell membrane that allows only some materials to pass through it?
Selective permeability is the property of the cell membrane that allows only certain molecules or ions to pass through, while blocking others. This is achieved through the presence of specific transport proteins and the lipid bilayer structure of the membrane.
What kind of permeablilty is it when a membrane only allows some materials to pass?
yes, they only allow water moleclues to pass through the membrane.
What is the drifference between a cell wall and a cell menbrane?
The cell wall is a protective layer of complex carbohydrates whereas the cell membrane is a lipo-protein membrane having property of selective permeability.
What is permeability for concrete?
Permeability is defined as the property that governs the rate of flow of a fluid into a porous solid.
The property of only allowing certain substances to move through it?
The property you are referring to is called selectivity. Selective membranes control the passage of substances, allowing only specific molecules or ions to pass through while blocking others based on their size, charge, or other characteristics. This selectivity is crucial in various biological processes and technologies like water filtration and gas separation.
