A selectively permeable cell membrane allows certain molecules or ions to pass through it by means of active or passive transport. The most common example is the phospholipid bilayer cell membrane that surrounds all of our body cells. The inner membranes of an egg are also selectively permeable membranes.
What else can I help you with?
Is a mirror selectively permeable?
A mirror is not selectively permeable. The mirror's surface is rigid since it cannot allow any substances to pass through it.
Is it true if the process by which water moves across a selectively permeable membrane is called diffusion?
Diffusion is a physical process. When it is performed through a selectively permeable membrane, it is called osmosis. Thus osmosis is an appropriate word for movement of water molecules through a selectively permeable membrane and not diffusion.
How does oxygen cross a selectively permeable membrane?
diffusion
Cells have selectively what membranes?
Cells have selectively permeable membranes that allow certain substances to pass through while blocking others. This selectivity helps maintain the internal environment of the cell by controlling the movement of molecules in and out.
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.
Cells have selectively what?
Selectively permeable.
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.
example of a common object that performs similarly to a selectively permeable membrane?
A paper filter
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.
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.
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.
Is a mirror selectively permeable?
A mirror is not selectively permeable. The mirror's surface is rigid since it cannot allow any substances to pass through it.
What does a selectively permeable membrane do?
A selectively permeable membrane allows some substances through it and does not allow others.Allows certain substances to pass but not others
Do all cells have a membrane?
Cells have impermeable, permeable and selectively permeable membranes.
