allowing some substance to pass into the cell and blocking others
The cell membrane is called semi-permeable because it allows certain substances to pass through while blocking others based on their size and properties.
One example of a semi-permeable membrane is the cell membrane in living organisms. It allows certain molecules to pass through while blocking others based on size, charge, and other factors. This selective permeability is essential for maintaining cellular functions and regulating the exchange of substances with the environment.
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)!!!
A membrane that only allows certain substances to cross is called a selectively permeable or semi-permeable membrane. It allows some molecules or ions to pass through while blocking others based on characteristics like size, charge, or solubility.
Osmosis can only occur if water travels through the semi-permeable membrane. This will cause water to cross the lipid bilayer.
It can permeate some stuff but not everything
The plasma membrane.
Such a membrane is said to be selectively permeable or semi-permeable.
Permeable mean that it is full time. Semi-permeable is when it is only part of the time.
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.
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 semi permeable membrane
semi permeable membrane is semi-permeable or not completely permeable...it allows particles of a certain shap or size flow through but other shapes that are large or snaller cant fit through.
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.
A semi-permeable membrane is a membrane which allows cells to pass through it. The cells which make up the membrane of the inside of the cheek of the human mouth, for example, are semi-permeable. This allows things, like nicotine for example, to be absorbed through the membrane walls while the walls maintain structural integrity.
