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 else can I help you with?
A membrane at the boundry of every cell that acts as a selective barrier?
The cell membrane is a phospholipid bilayer that acts as a selective barrier, controlling the passage of molecules into and out of the cell. It helps maintain cellular homeostasis by regulating the entry and exit of substances such as ions, nutrients, and waste products.
What is the layer of glycoproteins that prevents leakage of materials from connective tissues called?
The layer of glycoproteins that prevents leakage of materials from connective tissues is called the basement membrane. It acts as a selective filter, regulating the passage of substances between the connective tissue and the surrounding structures.
Which of these is involved in the manufacture of membrane?
Rough endoplasmic reticulum is involved in the manufacture of membrane. The plasma membrane is a selective barrier, regulating the passage of material into and out of the cell.
Organisms or fluids attempting to enter the cell body of a neuron must first pass through the?
cell membrane, which acts as a protective barrier around the neuron. This selective barrier controls the passage of substances in and out of the neuron to maintain its internal environment.
What is the structure and the function of the plasma membrane?
It has selective permeability (allows it to control what comes in and out of the cell) and it isolates the cytoplasm.
What is a selective barrier that regulats the passage of material into and out of the cell?
The plasma membrane
How is lipids suited to the function of the membrane?
It separates the cell from its surroundings and acts as a selective barrier to the passage of substances in and out of the cell

Why is the hydrophobic nature of lipids important?
The hydrophobic nature of lipids is important because it helps in forming cell membranes by creating a barrier that prevents the passage of water and water-soluble molecules. This selective barrier is essential for maintaining the internal environment of cells and for regulating the movement of substances in and out of cells. Additionally, the hydrophobic nature of lipids allows them to store energy efficiently in the body.
What does selectively perminable mean?
"Selectively permeable" refers to a membrane that allows certain substances to pass through while blocking others. This selective permeability is important for regulating the passage of molecules in and out of cells.

What allows item to pass in and out of nucleus?
The nuclear pore complex facilitates the passage of molecules in and out of the nucleus. It acts as a selective barrier, allowing specific molecules, such as RNA and proteins, to pass through while regulating the entry and exit of other molecules. This controlled movement is essential for cellular functions like gene expression and protein synthesis.
What does Selective permeability do?
It allows the passage for certain substances.
The blood-brain barrier is effective against the passage of?
The blood-brain barrier is effective against the passage of ? Metabolic waste such as urea
