plasma membrane allows water to enter animal cell

a membrane that only allows certain things to cross is called "selectively permeable"
the ability to allow materials to cross a membrane
As the cell membrane only allows certain substances to enter or leave the cell, meaning that while it IS permeable (as some substances can cross it), it is only selectively as not all substances are able to cross it, only some.
A membrane that lets some substances pass through but not others is known as a semipermeable membrane. Other terms that describe this type of membrane are: selectively permeable, partially permeable, or differentially permeable.
A semi-permeable membrane. Does cross - membrane transit of glucose need active transport,

Semi-permeable. Permeable means things can pass through, so semi-permeable means only some things can pass through.

In the field of biology Semipermeable and Selectively Permeable refer to what substances the cell membrane allows to permeate (cross) into and out of the cell. The two terms can be used interchangeably.
A membrane that lets all materials cross is permeable. A membrane that lets nothing cross is impermeable.
Animals have a cell membrane. This is like a skin that is semi-permeable and allows some things to cross, but not others.
