The cell membrane acts as the barrier and transport proteins present in the membrane, such as globular proteins, transport molecules across cell membranes.
The cell's membrane allows only certain substances to diffuse in and out of the cell.
The part that allows nutrients to enter the cell is the cell membrane. The cell membrane is a selectively permeable barrier that regulates the movement of substances in and out of the cell, allowing essential nutrients to enter while keeping harmful substances out. The nucleus and vacuole have different functions and do not play a direct role in nutrient uptake.
The cell membrane or cell wall.
The main function of the cell membrane is to regulate the movement of substances in and out of the cell. It acts as a barrier that allows essential molecules to enter the cell while keeping harmful substances out. Additionally, cell membranes also help maintain the cell's shape and provide structural support.
The cell membrane controls what substances enter or leave the cell. It is a selectively permeable barrier that allows certain molecules to pass through while blocking others. This regulation helps maintain the internal environment of the cell.
The cell part that allows only certain substances to diffuse into and out of the cell is called the semi permeable membrane. This allows good substances to enter the cell.
The cell's membrane allows only certain substances to diffuse in and out of the cell.
The cell membrane is the part of plant cells that regulates the movement of substances into and out of the cell. It acts as a barrier, allowing only specific molecules to pass through via various transport processes such as diffusion, osmosis, and active transport.
The cell membrane allows substances in and out of the cell and is a crucial part of homeostasis

The nucleus and vacuole have different functions and do not play a direct role in nutrient uptake.
Phospholipids
The plasma membrane / cell surface membrane. The phospholipid bilayer prevents certain substances passing straight through, so protein channels and other mechanisms control what does and does not pass in and out of the cell.
The cell membrane or cell wall.
The part of a cell that protects and supports it is the cell wall and the nucleus respectively. Every part of the cell has its unique function that allows the cell to survive.
The cell membrane, composed of phospholipids and proteins, allows for selective permeability. Its structure enables it to regulate the passage of molecules in and out of the cell, ensuring that only certain substances can cross based on their size, charge, and solubility.
it is the cell wall ! :)
