The permeability of a biological membrane is dependent on the type of transport proteins that are present in the membrane and the lipid bi-layer being permeable to primarily small, nonpolar molecules.

Selective permeable
selective permeability
Selective permeability refers to the property of the plasma membrane to allow certain substances to pass through while restricting others. This enables the cell to maintain an internal environment conducive to its function. The plasma membrane achieves selective permeability through various mechanisms such as protein channels and transporters.
Freezing can disrupt the structure of cell membranes, causing increased membrane permeability. This can lead to the leakage of cellular contents and potentially cell death. Additionally, ice crystal formation during freezing can physically damage cell membranes, further compromising their permeability.
Phospholipids make up cell membranes, specifically the phospholipid bilayer. This structure provides a barrier that separates the interior of the cell from the external environment, allowing for selective permeability and regulation of what enters and exits the cell.
Yes, it's a major factor in maintaining the internal environment of cells.
Selective permeable
The cell membrane controls selective permeability. Larger substances can enter the cell through endocytosis and exit through exocytosis.
GENETICS
A membrane is selectively permeable.
Capillary walls & Cell membranes
Selective permeability refers to the function of plasma membranes that is needed to maintain homeostasis in a cell and prevent foriegn substances from entering through the cells walls. Some molecules can pass, some are blocked
