the solubility theory of membrane permeability simply describes that a membrane can only be freely permeable to substances that can dissolve in it. this was the most basic theory posed to explain how substances passed through membranes of cells. another way of explaining this is that substances that can freely or passively diffuse across membranes when they have the same chemical or physical properties as the membrane.

What are facts about permeability?
Changes in permeability are changes in the number of compounds that can pass through a membrane. The presence of certain chemicals or radiation can change the permeability of a membrane.
What is the ability of a cell membrane to allow material to pass through it called?
permeability
What is cell membrane permeability?
It is the ability of the membrane to allow ions and/or particles to cross.
How does the permeability of the plasma membrane relate to homeostasis?

What membrane allows materials to pass into and out of the cell?
Permeability
What feature of a membrane describes whether molecules can cross the membrane?
permeabiity

What is the ability of a cell membrane to allow material to pass through it called?
permeability
What structure allows only certain things to pass in and out of a cell?
The cell membrane. It is a semi-permeable membrane (or selectively permeable membrane) - this means that it only lets certain certain molecules or ions pass in or out of the cell. Permeability may depend on the molecule's size, solubility, properties, or chemistry.
What are the six factors that influence the permeability of a cell membrane?
There are three factors that determine the permeability of a cell's membrane: 1. Total number of channels available 2. Conductance - how well an ion passes through the channel 3. How long the channels are open
Which feature of a membrane describes molecules whether can cross the membrane?
permeability
Which molecule of a membrane describes whether molecules can cross the membrane?
permeability
What does permeability depend on?
Permeability depends on membrane solubility and the presence of specific integral transport proteins. Other factors such as pressure, concentration, and temperature of the molecules or solutes on either side, as well as the size of the molecules can also affect permeability.

What is the permeability of the cell membranes?
A membrane is selectively permeable.
