What else can I help you with?
What is the funtion of the cell membrane?
The cell membrane acts as a barrier, controlling what enters and exits the cell. It also helps maintain the cell's shape and structure. Additionally, the cell membrane is important for cell communication and recognizing other cells or molecules.
What are the special structures in the cell membrane that allow materials such as water and sugar through made of?
PROTEIN!!!!!!!!!!!!!!!!!!!!!!!!!
What molecules in the cell membrane allow for passage of substances into and out of the cell?
Cell membrane
What of a cell allows material to enter and exit the cell?
Which statements describe the cell membrane? Check all that apply. It only allows certain materials to leave the cell. It allows all materials to leave the cell. It only allows certain materials to enter the cell. It allows all materials to enter the cell. It helps the cell get rid of waste. It brings waste into the cell for storage.
What regulates passage of materials into and out of cells?
The cell membrane, or plasma membrane, regulates the passage of materials into and out of cells through selective permeability. This means that only certain substances are allowed to pass through the membrane, while others are blocked or actively transported. This selective permeability helps maintain the internal environment of the cell and allows for proper function and communication with the external environment.
What are the holes in a cell membrane?
They are called porins and help in the transfer of materials in and out of the cell.
What is the nuclear pore used for?
The nuclear pores are tiny holes in the the nuclear membrane surrounding the nucleus of a cell, which allow the movement of solluable materials through the nuclear membrane, in and out of the nucleus.
What unwanted materials leave through the holes?
Unwanted materials such as waste products, toxins, and excess ions leave the cells through the holes in the plasma membrane. These holes include channels and transporters that allow the passive or active movement of substances in and out of the cell.
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 role nuclear pore?
Small holes in the nuclear membrane of a cell's nucleus, which allow the transportation of water solluable materials in and out of the nucleus through the nuclear membrane.
What is the ability of a cell membrane to allow materials to pass through?
permeability
Can substances move in and out of the cell membrane?
Yes, how else could the cell live. Cell membranes have structures (holes) in them to allow things to move in and out. These holes are special structures in the membrane and they "control" what goes across the membrane. I have made a link below to a diagram of the cell membrane to show some of these structures.
What are the holes in the mitochondria of an animal cell called?
They are not holes.They are membrane proteins.
What is the ability of a cell membrane to allow materials to pass through called?
permeability
What is the ability of a cell membrane to allow materials to pass through it is called?
permeability
Which part of the cell surrounds the cell and allows molecules in and out this cell part also has holes in it and is said to be semi-permeable?
The cell membrane is the thing that surrounds the cell. The cell membrane contains proteins that allow active transport of molecules in and out of the cell.
What cell allows 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.
