What is the outer layer of a cell that acts as a gatekeeper to a cell?
The outer layer of a cell that acts as a gatekeeper is called the cell membrane. It regulates the movement of substances in and out of the cell to maintain internal balance.
The plasma membrane of a human cell does what?
acts as a gatekeeper
What The outer layer of a cell that acts as a gatekeeper to a cell is the?
Plasma membrane
What is the primary boundary of the cell and what is the overall security of the cell?
For an animal cell it is the cell wall. For a plant cell it is the cell membrane. In an animal cell the cell membrane is right inside the cell wall. The cell membrane is known as "The Gatekeeper" and is the main security of the cell.
Which structure is a gatekeeper controlling what goes in and out of the cell?
That would be the "guard cells". The stoma is an opening on the underside of many leaves and each stoma is bordered by a pair of guard cells that open and close the pore to allow for "transpiration" (the passage of water in either gaseous or liquid form into or out of the leaf). In hot, dry weather, the guard cells close to prevent water loss. In humid weather, the guard cells allow the pore to open and water can enter.
What is the cell membrane referred to?
Plasma membrane.The cell membrane also called the plasma membrane or plasmalemma is the biological membrane separating the interior of a cell from the outside environment.
What cell feature has been called 'Not just a bag but a fluid mosaic gatekeeper'?
The cell membrane is often referred to as "not just a bag but a fluid mosaic gatekeeper." This description highlights its dynamic nature, with proteins and lipids constantly moving within the membrane, allowing it to regulate the flow of molecules in and out of the cell. It serves as a selective barrier that controls the passage of substances into and out of the cell.
Did organelle is like the gatekeeper of the cell?
The organelle that functions like the gatekeeper of the cell is the cell membrane, also known as the plasma membrane. It regulates the entry and exit of substances, maintaining the cell's internal environment by allowing selective permeability. This ensures that essential nutrients can enter while waste products and harmful substances are kept out. Additionally, the cell membrane plays a role in cell signaling and communication with other cells.
What is the key function for a cell membrane?
The key function of a cell membrane is to regulate the passage of molecules in and out of the cell. This selective permeability helps maintain the internal environment of the cell and allows it to communicate with its surroundings.
What is a simile for the cell membrane?
a cell wall is like skin. skin protect and support our muscle and bone and when the cell wall protects and supports the cell
What object can a cell membrane be?
A cell membrane can be compared to a barrier or a gatekeeper. It regulates the movement of substances in and out of the cell, maintaining internal conditions necessary for the cell to function properly.
What is the outer layer of a cell that acts as a gateskeeper?
The outer layer of the cell is the cell membrane. This membrane is made up of phospholipids which themselves are made of a polar phosphate head and a non-polar fatty acid tail. The polar heads face the exterior and interior of the cell while the fatty acid tails comprise the interior of the membrane that is created by this arrangement. The membrane acts like a "gatekeeper" for 2 reasons: 1) water and ions can diffuse freely across the membrane while larger molecules cannot 2) a vast variety of proteins are embedded in the membrane and they allow certain ions and even larger molecules to flow to the interior of the cell. This "gatekeeper" function is important for maintaining the cells internal activities.
