What is the cell membrane which means that some substances can pass through it while others can't?
Semipermeable membrane.
What kind of protein helps some substances cross the cell membrane?
Channel proteins.
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.
The cell membrane forms a protective barrier between the external and internal environments. It is referred to as because it allows some substances to cross more easily than others and blocks other su?
The affirmation is correct.
What is the cell membrane which makes some substances can pass through it while others cannot?
The phospholipid bi-layer.
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 does a selectively permeable membrane do?
A selectively permeable membrane allows some substances through it and does not allow others.Allows certain substances to pass but not others
What is the cell membrane which means that some substances can pass through it while others can't?
Semipermeable membrane.
What kind of protein helps some substances cross the cell membrane?
Channel proteins.
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 characteristics of cell membrane allows for some substances to pass through but not others?

What is selectively permeable?
The property of a membrane or other material that allows some substances to pass through it more easily than others.Selective permeability refers to the control that a cell membrane has in terms of what it allows to cross it. This gives the cell membrane the ability to choose which molecules enter or leave.
What properties does a selective permeable membrane have?
the ability to allow materials to cross a membrane
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.
When some substances can pass across them but others cannot?
membrane
How does the composition of the cell membrane help regulate the movement of substances into and out of the cell?
They pass through channels in the cell membrane.
The cell membrane forms a protective barrier between the external and internal environments. It is referred to as because it allows some substances to cross more easily than others and blocks other su?
The affirmation is correct.
