No, cell membranes are semi-permeable, meaning they allow some solutes to pass through - but not others.
Diffusion across a membrane in biology is referred to as 'osmosis' & osmosis is the process by which solvent molecules move from a region of high conc. to low concentration and this can therefore occur only in one direction at a time for a perticular solution. this is a really smart answer im surprised
Yes, it is a partially permeable membrane. It allows certain substances like glucose and water molecules to diffuse through but not large molecules like starch and sucrose. Selectively permeable.
Osmosis is the diffusion of molecules from where they are abundant to where they are scarce through a semi permeable membrane. In red blood cells, this semi permeable membrane is the cell membrane. If red blood cells were placed in a solution abundant with water molecules, they would diffuse into the cells through the membrane
the ability to allow materials to cross a membrane

Selectively permeable means that only certain substances are able pass through the cell membrane.A selectively permeable membrane is a membrane that only can be permeated by selective things, in other words a surface that lets some molecules in but not others. Like a cell membrane will let water diffuse into it :)
The membrane is semi-permeable. Sugar molecules are too large to diffuse through.

means that the cell membrane has some control over what can cross it, so that only certain molecules either enter or leave the cell

very complicated question that is better addressed by a cell biology text but in general cell membrane itself is non-polar and allows small non-polar molecules through it also has protein that are built to selectively let in molecule based on commands from the body
The movement of water through a selectively permeable membrane is called diffusion. Water will always diffuse down a concentration gradient, from high solute concentration to low solute concentration.
selectively permeable or selective permeability
is based on diffusion of waste substances through a selective permeable membrane
