What is a membrane called when only certain things can cross a membrane?
A membrane that only allows certain substances to cross is called a selectively permeable or semi-permeable membrane. It allows some molecules or ions to pass through while blocking others based on characteristics like size, charge, or solubility.
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.
What properties does a selective permeable membrane have?
the ability to allow materials to cross a membrane
Why is a cell membrane called semi-permeable or selectively permeable?
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.
What is the membrane called if other substances besides water oxygen carbon dioxide and glucose are blocked from entering?
The membrane is selectively permeable if it only allows certain substances like water, oxygen, carbon dioxide, and glucose to pass through while blocking others based on size, charge, or other properties.
What process allows water to cross the selectively permeable membrane of an animal cell?
Mitosis
What process allows water to cross selectively permeable membrane of an animal cell?
Mitosis
What type of membrane allows some but not all materials cross?
A selectively permeable membrane allows SOME but not ALL materials to cross.
What is a membrane called when only certain things can cross a membrane?
A membrane that only allows certain substances to cross is called a selectively permeable or semi-permeable membrane. It allows some molecules or ions to pass through while blocking others based on characteristics like size, charge, or solubility.
What property in the cell membrane that allows only some substances in?
Semi-permeable. Permeable means things can pass through, so semi-permeable means only some things can pass through.
How does oxygen cross a selectively permeable membrane?
diffusion
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.
What is the definition of impermeable?
A membrane that lets all materials cross is permeable. A membrane that lets nothing cross is impermeable.
What properties does a selective permeable membrane have?
the ability to allow materials to cross a 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.
