A selectively permeable cell membrane allows certain molecules or ions to pass through while restricting the passage of others. This selective permeability helps regulate the movement of substances in and out of the cell, maintaining internal conditions necessary for cellular functions.

What does it mean if a cell is selectively permeable?
In Biology, a selective permeable cell means the cell only allows certain molecules to pass through. This concept was first introduced to understand the process of osmosis, where solute molecules move along a concentration gradient through a semi permeable membrane (also known as a selectively permeable membrane) Cells allow water molecules and small ions to pass through their membranes without the expenditure of energy.
What does it mean to be selectively permeable semi-permeable?
Being selectively permeable or semi-permeable means that a membrane allows some substances to pass through while restricting the passage of others based on size, charge, or other properties. This selectivity enables the membrane to regulate the movement of molecules and ions in and out of cells or compartments, maintaining homeostasis and enabling essential biological processes.
What does the term selectively permeable mean?
Selectively permeable refers to a membrane that allows certain substances to pass through while blocking others based on their size, charge, or solubility. This property enables cells to regulate the movement of molecules in and out of the cell to maintain proper balance and homeostasis.
What does it mean that the cell membrane is selectively permeable?
It means that the cell membrane allows some substances to pass through while blocking others. This property helps regulate what enters and exits the cell, maintaining the balance of molecules and ions inside.
What is osimosis?
I'm not sure what you meant by "osimosis." If you are referring to osmosis, it is the movement of water across a selectively permeable membrane from an area of high concentration to an area of low concentration. This process helps to balance the concentration of solutes on both sides of the membrane.
The cell membrane is selectively permeable. What does that mean?
Because plasma membrane allows only certain solute to move into the cell and outside the cell
What does the term permable mean?
Selectively permeable refers to a cell membrane that will let certain things in and out of the cell, but block other things.
Does it mean for a cell membrane to be selectively permeable?
it allows some substances to pass through but blocks the passage of others.
What does it mean that biological memberanes are selectively permeable?
it means that any biological membrane allows only certain solute or we can say nutrients that are required by cell, to enter into cell through itself and not other unnecessary particles hrmful to cell.. Such property is called selectively permeable or semi permeable...
What is an example of active transport through a cell membrane?
Osmosis. Osmosis is the diffusion of water through a selectively permeable membrane. I'm assuming you mean active transport of plasma into a red blood cell.
What does the term selectively permable mean?
"Selectively permeable" refers to a membrane that allows certain substances to pass through while blocking others. This selectivity is based on the size, charge, or other properties of the molecules trying to cross the membrane. An example is a cell membrane, which permits the passage of specific molecules necessary for the cell's function while blocking others.
What does it mean for phospholipid membrane to be selectively permeable?
It only let's some materials pass in and out.

Is the cell membrane permeable in animal cells?
I assume you mean semi-permerable membrane that is permeable to the solution (water) but not the solute (salt). Osmosis can only occur if the membrane does NOT allow salt to pass through. Osmosis is the movement of water across a semi-permeable membrane from an area of low salt concentration to higher salt concentration.
What does it mean for a cell membraneto be selectively permeable?
it blocks the passge of most substances
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.
