What else can I help you with?
What structure acts as a selective barrierregulating the traffic of materials into and out of the cell?
Cytoplasm is the selectively permeable structure that separates intracellular material from extracellular material.
What is the molecule surrounding DNA?
The molecule surrounding DNA is called histones. Histones are proteins that help organize and package DNA into chromatin, which is the complex structure that makes up chromosomes. Histones play a crucial role in regulating gene expression and maintaining the structure of DNA within the cell.
What structure regulates the traffic of materials into and out of the cell?
The cell membrane, also known as the plasma membrane, regulates the traffic of materials into and out of the cell. It acts as a selectively permeable barrier that allows certain substances to pass through while restricting others.
What color is the nuclear envelope?
The nuclear envelope is typically colorless and not visible under normal circumstances. It is a double membrane structure surrounding the nucleus of a cell and is involved in regulating the passage of molecules in and out of the nucleus.
What membrane allows materials to pass into and out of the cell?
The cell membrane, also known as the plasma membrane, is a selectively permeable barrier that regulates the passage of materials in and out of the cell. Its structure consists of a lipid bilayer with embedded proteins that facilitate the transport of substances such as nutrients, waste products, and signaling molecules.
What structure involved in regulating the movement of materials into a cell is?
cell membrane
What cell structure is responsible for regulating the materials that enter and exit the cell?
cell membrane
What structure helps cells maintain homeostasis by regulating the movement of materials into and out of the cell?
cell membrane
What structure acts as a selective barrierregulating the traffic of materials into and out of the cell?
Cytoplasm is the selectively permeable structure that separates intracellular material from extracellular material.
What is one main difference between the cell wall and the cell membrane?
One main difference is that the cell membrane is a selectively permeable barrier surrounding the cell, regulating the passage of substances in and out, while the cell wall is a rigid structure located outside the cell membrane that provides support and protection to the cell.
What is the molecule surrounding DNA?
The molecule surrounding DNA is called histones. Histones are proteins that help organize and package DNA into chromatin, which is the complex structure that makes up chromosomes. Histones play a crucial role in regulating gene expression and maintaining the structure of DNA within the cell.

Double layered membrane with pores surrounding the nucleus?
The double-layered membrane surrounding the nucleus is called the nuclear envelope. It has pores called nuclear pores which allow the movement of molecules like RNA and proteins in and out of the nucleus while regulating the passage of larger molecules. This structure helps to protect and regulate the contents of the nucleus.
What membrane allows materials to pass into and out of the cell?
The cell membrane, also known as the plasma membrane, is a selectively permeable barrier that regulates the passage of materials in and out of the cell. Its structure consists of a lipid bilayer with embedded proteins that facilitate the transport of substances such as nutrients, waste products, and signaling molecules.
What structure controls the movement of materials into and out of all cells?
The cell membrane, also known as the plasma membrane, controls the movement of materials into and out of all cells. It is a selectively permeable barrier that regulates the passage of substances in and out of the cell to maintain internal homeostasis.
What is cell membrane explain in urdu?
plasma membrane is the outer most boundary of animal cell.it is chemically composed of lipids and proteins.it is selectively permeable allow certain materials to move in and out.fluid mosaic modle explain its structure.
