The cell membrane is selectively permeable because it allows certain molecules to pass through while blocking others. This selectivity is maintained by the presence of proteins and channels that regulate the passage of substances in and out of the cell. This selective permeability is essential for maintaining cellular homeostasis and regulating cell functions.

What does it mean if a cell membrane is selectively permiable?
The cell membrane only allows certain molecules through.
What membrane allows only some materials to move in and out of the cell?
The cell membrane, which is a lipid bilayer, will only allow some things in and allow others to go out of the cell.
What is the term used for a layer that allows only certain molecules to pass through the cell membrane?
permiable
What will happen if a partially permiable membrane is replaced with a non permiable membrane?
If a partially permeable membrane is replaced with a non-permeable membrane, no substances will be able to pass through the membrane. This will prevent the movement of molecules across the membrane and alter the osmotic balance between the two sides of the membrane. This could lead to changes in cell volume and affect cellular processes that rely on osmotic balance.
How does the cytoplasm regulate?
No. The Endoplasmic Reticulum moves things throughout the cell, and the Cell Membrane controls what enters the cell, and what leaves. That means that the Cell Membrane is semi-permiable.
What does it mean if a cell membrane is selectively permiable?
The cell membrane only allows certain molecules through.
Which cell part determines what molecules move into or out of the cell?
The Semi-Permiable Cell Membrane

What is the term used for a layer that allows only certain molecules to pass through the cell membrane?
permiable
Why will the cell not burst?
animal cells do no burst because the semi permiable membrane lets little water in so the cell does not become turgid.
What is it called when a cell membrane closes around a molecule to allow the molecule to enter the cell?
This process is called endocytosis. It involves the cell membrane engulfing and enclosing the molecule or particle in a vesicle to transport it into the cell.

What is the purpose or function of the cell membrane?
the cell membrane of a cell controls what enters and exits the cell so in theory the cell membrane acts as if it were a shield blocking harmful things from entering the cell and lets nutrients in.
Which part of the plant cell is fully permiable?
cell wall
