very complicated question that is better addressed by a cell Biology text but in general
cell membrane itself is non-polar and allows small non-polar molecules through
it also has protein that are built to selectively let in molecule based on commands from the body

Which layer controls selective permeability?
The cell membrane controls selective permeability. Larger substances can enter the cell through endocytosis and exit through exocytosis.
When would you want to use selective media?
Selective Media - Our cell membrane has a selective permeable property. This type of membranes are important when we want to allow certain sized particles to enter while restricting other sized particles to enter our cell. Selective permeable membrane is of great use in biological samples.
What makes up a selectively permeable membrane?
Plasma membrane filters what the cell needs and keeps out what will harm it. this property is called selective permeability.
A thin layer covering the outside of cells?
The thin layer covering the outside of cells is called the cell membrane or plasma membrane. The cell membrane is a vital component of all cells, whether they are prokaryotic (lacking a nucleus) or eukaryotic (containing a nucleus). It serves as a selective barrier that separates the internal environment of the cell from the external environment, controlling the passage of substances in and out of the cell. The cell membrane is primarily composed of lipids (such as phospholipids), proteins, and carbohydrates. The phospholipid bilayer forms the basic structural framework of the membrane, with proteins embedded within or attached to the surface. These proteins play various roles, including transport of molecules, cell signaling, and maintaining the structural integrity of the membrane. Overall, the cell membrane is crucial for maintaining cellular homeostasis and allowing cells to interact with their surroundings while protecting their internal components.
What is the outer layer of a cell?
The outer layer of a cell is the cell membrane or plasma membrane
Which cell structure controls what enters and leaves the cell?
The selective permeability of the cell membrane
Which part of the cell allows for selective permeability?
Cell membrane
What is a selective barrier regulating the passage of materials into and out of the cell?
In a plant cell, this selective barrier is known as the cell membrane but also a plant cell has a cell wall. The cell membrane is semi permeable allowing only certain materials so the cell membrane allows in materials and the cell wall ''digests it''. While in a plant cell does not have a cell wall only a cell membrane.It is the cell membrane that acts as its selective barrier.
What controls what passes in and out of cells?
Through something called "Selective permeability"
What part of the cell is a selective permeable membrane?
The phospholipid bilayer. plasma membrane
What type of cell has a selective membrane?
Eukaryotic cells
What is the characteristic of a cell membrane that controls which substances that can either enter and exit the cell?
Selective permeable
How does a cell control what enters and leaves?
The cell membrane enables a cell to control what enters and leaves. The membrane has a selective semi-permeable membrane which facilitate this process.
Selective permeability refers to the fact that the plasma membrane keeps all molecules out of the cell?
Selective permeability refers to the fact that the plasma membrane can choose which molecules to let in or out of the cell.
What property of the cell membrane allows it to maintain cell homeostasis?
Selective Permeability
A membrane at the boundry of every cell that acts as a selective barrier?
The membrane at the boundary of every cell that acts as a selective barrier is called the cell membrane. The cell membrane is made of compounds called proteins and lipids.
How is the membrane permeability?
means that the cell membrane has some control over what can cross it, so that only certain molecules either enter or leave the cell
