The cell membrane regulates the movement of substances in and out of the cell.
How does it do this? The phospholipid bilayer is impermeable to most substances, allowing across only small, uncharged molecules such as those of oxygen, carbon dioxide, and water. The only way for other substances to cross the membrane is via transport proteins (channel and carrier proteins). These are selective, and therefore control what enters and what leaves the cell.
What else can I help you with?
What is the barrier around the that lets substances move across it?
Cell membrane is the barrier around the cell that allows certain substances to move across it. It is selectively permeable, meaning it controls the movement of molecules in and out of the cell. This helps maintain the internal environment of the cell and ensures proper functioning.
What is the job of cell membrane?
Cell membreneA layer that controls what enters and what leaves the cell. Or a protective covering enclosing the entire cell.(controls substances going in and out of the cell.)
What part of a cell controls substances moving in and out?
The cell membrane is reposnible for allowing what substances can enter and leave a cell, this happens by different methods of transport for instance "active transport" in plants. The phospholipid bilayer containing cholesterol, proteins and carbohydrates, also helps in allowing which substances to pass.
The cell membrane controls what goes in and out of the cell true or false?
True. The cell membrane is selectively permeable, meaning it regulates the movement of substances in and out of the cell to maintain internal balance and protect against harmful substances.
What is called when vesicles are used to move substances out the cell?
Exocytosis
What controls which substances can move in and out of cells?
Cell membrane controls which substances can move in and out of a cell. It is the dynamic boundary of cell
What Controls what moves into cells?
The Cell Membrane is usually attributed with controling which substances can move in and out of the cell.
The protective covering that allows materials to move into and out of a cell is the?
The cell membrane is the barrier that controls what substances enter and leave a cell.
What part of the cell controls the diffusion of substances into and out of the cell?
it is the cell wall ! :)

Cell membrane is the barrier around the cell that allows certain substances to move across it. It is selectively permeable, meaning it controls the movement of molecules in and out of the cell. This helps maintain the internal environment of the cell and ensures proper functioning.
What controls movement of substances in and out of the cell?
osmosis
What functions of the cell membrane do for the cell?
It controls the entry and exit of substances.
What is the property that allows only some substances in and out of a cell.?
The permeability of the cell membrane controls which substances may pass in or out of the cell.

What is the function of a cell membrane in a plant?
The cell membrane controls the movement of substances into and out of the cell.
What does a cell membrane do in a root hair cell?
a cell membrane controls movement of substances in and out of the cell.
