GENERAL HISTOLOGY

Detailed explanation-1: -The cell membrane is called selectively permeable as it only allows specific molecules to pass. Only specific molecules like water and gaseous molecules can pass through the cell membrane directly. It stops the flow of other molecules towards the two sides.

Detailed explanation-2: -Cell membrane or plasma membrane is described as a selectively permeable membrane.

Detailed explanation-3: -Being selectively permeable allows the cell to bring in molecules it needs and exclude molecules it does not. It also allows the cell to control when certain molecules move into or out of the cell. This allows for complex signaling cascades that regulate cell function.

Detailed explanation-4: -The membrane’s lipid bilayer structure provides the first level of control. The phospholipids are tightly packed together, and the membrane has a hydrophobic interior. This structure causes the membrane to be selectively permeable.

Detailed explanation-5: -The cell wall is freely permeable.
