What else can I help you with?
What covers a cell?
The cell membrane, also known as the plasma membrane, covers and protects a cell. It controls what enters and leaves the cell, allowing for communication and maintaining the cell's internal environment.
How is the phopholipid bilayer involved in the passage of materials in and out of cells?
It hold the structure of the cell together. It also regulate what enters and exits the cell.
What organelles controls what enters and exits the cell?
The Cell membrane.
What are human cells always surrounded by?
Human cells are always surrounded by a cell membrane, also known as the plasma membrane. This thin, semi-permeable barrier controls what enters and exits the cell, helping to maintain the cell's internal environment and regulate communication with other cells.
Which structure in the cell membrane acts as a door and controls what enters and leaves a cell?
Cell membrane
What covers a cell?

The controls what enters and leaves?
cell membrane
What is the structure that surrounds a cell and controls what enters and leaves the cell?
The cell membrane is the structure that surrounds a cell and controls what enters and leaves the cell. It is made up of a lipid bilayer with embedded proteins that selectively allow certain molecules and ions to pass through the membrane.
What controls what goes in and out of the plant cell?
yes
What controls the passage of nutrients in and out of the cell?
The cell membrane controls what enters and exits a cell.
What is the difference between the cornea and iris?
The cornea is the surface of the eye. It is completely transparent, as all light that enters the eye must pass through the cornea. If you look at a person's eye from the side, you will see some clear material covering the front of the eyeball. That is the cornea. The iris is what controls the amount of light let into the eye. It is what gives the eye its colour, and it is what actually controls the size of the pupil.
What surrounds the nucleus and controls and what enters and leaves it?
The nucleolus .
Can everything move in or out of the cell?
No, the cell membrane, which is a phospholipid bilayer of embedded proteins, regulates what enters and leaves the cell.
What organelle controls what enters and leaves the nucleus?
nuclear ,membrane
The primary structural component of a cell membrane is?
phospholipids. They form a lipid bilayer that surrounds the cell, providing a barrier that controls what enters and exits the cell. Additionally, proteins embedded in the phospholipid bilayer play a crucial role in facilitating various cellular processes.
What surrounds the nucleus and and controls what enters and leaves it?
Cell wall
What surrounds the nucleus and controls what enters and leaves the nucleus?
The nucleolus .
