What is an example of a permeable membrane?
Examples of Selectively Permeable Membranes The most common example is the phospholipid bilayer cell membrane that surrounds every cell in our bodies. Another example of a selectively permeable membrane is the inner membranes of an egg. All cells in our body are surrounded by a phospholipid bilayer.
What are three examples of a selectively permeable material or item?
Examples of selectively permeable materials or items are;
- Vacuum filter- it traps dust but allows air through.
- Coffee filter- allows water to pass through, but does not allow the coffee grounds.
- Colander -used to strain liquid food from foods. it drains water but is not permeable to larger food particles.
What is a selectively permeable material?
Selectively permeable means a membrane allows the passage of some molecules or ions and inhibits the passage of others. The capacity to filter molecular transport in this manner is called selective permeability.
Is plastic permeable?
In contrast to glass or metal packaging materials, packages made with plastic are permeable at different degrees to small molecules like gases, water vapour, and organic vapour and to other low molecular weight compounds like aromas, flavour, and additives present into food.
Are ribosomes partially permeable?
Ribosome-stripped ER membranes are permeable to small molecules.

What is an example of something in everyday life that is like a semi permeable membrane?
Salt on Slugs The moist skin of a slug act as a semipermeable membrane. The high concentration of salt on the slug’s skin draws water out of its cells through osmosis. The water comes out because this equalizes salt concentration between the outside and inside of the slug’s skin.
