What does it mean to say most biological membranes are selectively permeable?

Selectively permeability is a property of biological membranes that allows them to regulate the passage of substances across them. In spite of heavy traffic through them, cell membranes are selectively permeable, and substances do not cross the barrier indiscriminately.

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 is the difference between a semi-permeable and a partially permeable membrane?
An impermeable membrane is that through which no substance can pass. Semipermeable membranes are those that let only solvents, like water, to pass through it. Permeable membranes are those that let solvent and solutes, like ions and molecules, to pass across it. There are also selectively permeable membranes, i.e., membranes that besides allowing the passage of solvent, let only some specific solutes to pass while blocking others. See link:
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)!!!
What 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 the term selectively permeable mean?
If you break down the two words, selective means to only pick certain things, and permeable means to let pass through. When you talk about something being "selectively permeable", it usually refers to a cell membrane because it only lets in certain nutrients and lets out proteins and what not. I hope this answers your question.
Does it mean that biological membranes are selectively permeable?
means they allow some things to cross, but not 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...
Does selectively permeable and semi permeable mean the same thing?
nope

2 examples of partially permeable membranes?
A selectively permeable membrane is most often attributed to the cell membrane (plasma membrane) of cells. It is constructed of nonpolar phospholipids that will not dissolve many substances, like ions or large molecules. There are carrier proteins embedded in the membrane that allow only certain substances through.
