non penetrating substances may have molecules too large to go through a membrane or are chemically repelled by the membrane so it can't go through.

What is a membrane that allows some substances to pass through but excludes others?

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.


Define selectively permeable?

A selectively permeable membrane allows certain substances to pass through while restricting the passage of others based on size, charge, or other properties. This property is important for controlling the movement of molecules in and out of cells and organelles.


What does it mean for a cell membraneto be selectively permeable?

A barrier that allows some substances in while keeping other substances out is said to be?

Semipermeable membrane.


Cells have selectively what membranes?

Cells have selectively permeable membranes that allow certain substances to pass through while blocking others. This selectivity helps maintain the internal environment of the cell by controlling the movement of molecules in and out.


Why would cell membrane be destroyed if if it were permeable instead of selectively permeable?

Unwanted substances could get in, potentially destroying the cell and membrane.


What do the terms semipermeable and selectively permeable refers to?

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.


Can you explain how a selectively permeable membrane functions?

A selectively permeable membrane allows certain substances to pass through while blocking others based on their size, charge, or other properties. This selective process helps regulate the movement of molecules in and out of cells or compartments, maintaining balance and allowing essential processes to occur.
