What does having selectively permeable membrane mean?

Having a selective permeable membrane means that the membrane allows specific substances to pass through it while keeping others out. The membranes are created using a specific method to create pores in the membrane, and these pores are of a specific size to let certain substances through while keeping others out. The porosities of these membranes are different.

What does selectively permeable membrane mean?

A selectively permeable membrane is a biological or man-made barrier that allows certain substances to pass through it, while keeping others out. There are five main types of selectively permeable membranes: porous, semipermeable, ultraporous, active and passive. Porous membranes are the most common. They are made from a material that allows air and moisture to pass through it but stops larger particles. These membranes are often used in filters, food packaging, water purification systems and medical applications.

What does a selectively permeable membrane mean?

A selectively permeable membrane is designed to allow certain substances in, while rejecting others. The properties of a permeable membrane can vary depending on the type of membrane and the substances it was designed to block.

What does selectively permeable membrane mean in biology?

A selectively permeable membrane is a biological structure that allows specific substances to pass through it while keeping other substances out. For example, cell membranes allow nutrients to enter a cell, but keep the cell and its contents separate from the environment.

What does selectively permeable membrane mean in English?

A selectively permeable membrane is one that can allow certain substances to pass through it while stopping others. An example of a selectively permeable membrane is a coffee filter, which allows water to pass through it while stopping ground coffee from passing through it.
