Selective permeability relates to the properties of a membrane. It allows the passage of some substances and not others. Theoretically, it can be thought of as a sheet with holes of a set size in it. Only objects that are smaller than these holes will be able to pass through the sheet.
In a proper membrane the 'holes' are usually a type of protein channel that can control permeability by charge as well as size.
What else can I help you with?
A membrane that allows some substances to pass through while excluding others would be called a?
semipermeable or selectively permeable.
What is a membrane that allows some substances to pass through but excludes others?
A membrane that lets some substances pass through but not others is known as a semipermeable membrane. Other terms that describe this type of membrane are: selectively permeable, partially permeable, or differentially permeable.
What does it mean to be selectively permeable semi-permeable?
DefinitionnounA membrane that is selectively permeable, i.e. being permeable to only certain molecules and not to all molecules.SupplementAn example of such membrane is the cell membrane wherein it allows passage of only certain types of molecules by diffusion and occasionally by facilitated diffusion.by~paula razon (facebook)!!!
Is the cell membrane selectively permeable?
There are different types of plastics and most of them are nor permeable or selectively permeable .Cellophane is a specific plastic used in biological experiments as it is selectively permeable .
Define selectively permeable?
A selectively permeable membrane allows certain substances to pass through while restricting the passage of others based on size, charge, or other properties. This property is important for controlling the movement of molecules in and out of cells and organelles.
Cells have selectively what?
Selectively permeable.
Does selectively permeable and semi permeable mean the same thing?
Yes, selectively permeable and semi-permeable mean the same thing. They refer to a membrane that allows certain molecules or ions to pass through while blocking others based on size, charge, or other properties.
A membrane that allows some substances to pass through while excluding others would be called a?
semipermeable or selectively permeable.
What is definition of selectively permeable?
The selectively permeable phospholipid bilayer (a.k.a plasma membrane) is 'selectively permeable' because it selects which molecules it allows to permeate (pass through).
What is the relationship between cell membrane and selectively permeable?
Cell membranes are indeed selectively permeable.
What does it mean for a cell membraneto be selectively permeable?
it blocks the passge of most substances
How is dialysis membrane selectively permeable?
a dialysis membrane is selectively permeable, it is used in experiments to simulate cellular membranes, and it is permeable to water but not to sucrose.
What does it mean for phospholipid membrane to be selectively permeable?
It only let's some materials pass in and out.
Does the membrane of a cell is selectively permeable?
no
What is the basic strcture of a cell membrane?
Cell membrane is elastic and transparent. It can be impermeable, permeable, semi-permeable or selectively permeable. In humans the plasma membrane is selectively permeable that is it allows entry to certain substance.
Does it mean that biological membranes are selectively permeable?
means they allow some things to cross, but not others.
Are cell walls and cell membranes selectively permeable?
Cell membranes are selectively permeable while cell walls are semi-selectively permeable. Keep in mind that only low level organisms, like plants, have cell walls.
