I impermeable membranes I think are these which dont allow the entry of even the solvent molecules and that kinna example can be seen in the plants. The cells with suberin and lignin covering act as impermeable membrane and do not allow water molecules to tranport through it.

cell membrane
Hi
A membrane that surrounds the nucleus of a cell.
A membrane that lets all materials cross is permeable. A membrane that lets nothing cross is impermeable.
The official definition for the word ofendocytosis is "the taking in of matter by a living cell by invagination of its membrane to form a vacuole."

Animal cells are typical of the eukaryotic cell, enclosed by a plasma membrane. It contains a membrane bound nucleus and organelles.
Infllammation of the nose; esp., inflammation of the mucous membrane of the nostrils.
Did you mean exocytosis? if so, the definition is a process by which the contents of a cell vacuole are released to the exterior through fusion of the vacuole membrane with the cell membrane.
it is the boundry of control of what enters and exit the cells
Membrane active drugs are compounds that target and interact with cell membranes, disrupting their structure or function. These drugs can affect essential processes such as cell signaling, transport, or membrane integrity, leading to various pharmacological effects. Common examples include antibiotics, antifungals, and some anticancer agents.
