It can permeate some stuff but not everything
The plasma membrane.
Such a membrane is said to be selectively permeable or semi-permeable.
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.
Permeable mean that it is full time. Semi-permeable is when it is only part of the time.
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.
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.
a semi permeable 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.
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.
A semi-permeable membrane, permeable to gases and small, non-charged particles.
A semi-permeable membrane, permeable to gases and small, non-charged particles.
It means that is/can be a door to a cell 'hence semi permeable membrane? (or to anything)
