Best Answer

it controls what enters and exits the cell

----------------------------------------------------------------

It holds the cell contents together and forms a barrier between these contents and what is outside the cell. It also has structures in it that allow for the controlled transport of specific substance into and out of the cell.

The cell membrane acts as a barrier, regulating the passage of materials in and out of the cell. It also helps maintain the cell's shape and provides structural support. Additionally, the cell membrane contains proteins that facilitate cell-cell communication and recognition.

Basically to keep the insides in. But it is not just a passive skin. it is actually a fluid bilayer of lipids with hydrophilic ends on the outside. This membrane is thus active, being penetrated by protein complexes that determine what substances are allowed in and what is allowed out.

Also, the outer layer is occupied by glycoproteins that have attached sugars, and these act as a kind of fingerprint of the cell, allowing it to be recognised by other cells and important compounds like hormones. It lets some molecules in and keeps some out For example, the cell membranes of the villi in the small intestine let nutrient molecules into the bloodstream, but leave the large ones out.

What role do membranes play in prokaryotes?

Prokaryotic cells do not have membrane bound organelles. The membrane controls the movement in and out of the cell.


What role do the cell wall and cell membrane play in a cell?

It is important to remember the following: Animal cell: Cell membrane, Plant cell: Cell membrane, cell wall. The role of a cell membrane is to monitor what exits and enters the cell and therefore maintain the internal environment of it, to contain the contents of the cell and to provide some sort of protection for it. The role of a cell wall which is unique only to plant cells, is to protect the cell inside and lend support to it so it can maintain its stucture.


What is the function of the specific carbohydrates that are attached to the cell membrane?

Carbohydrates on the cell membrane play a role in cell recognition and communication with other cells. They can also act as receptors for signaling molecules and help stabilize membrane protein structures. Additionally, these carbohydrates can be involved in immune response and can play a role in determining blood type.


What are organelles that play a major role in the cell division?

The cell membrane. But if the cell is a plant cell, the cell membrane and cell wall work together to accomplish this task.


What are some of the lipids found in a Cell membrane?

Some of the lipids found in a cell membrane include phospholipids (such as phosphatidylcholine and phosphatidylethanolamine), glycolipids, and cholesterol. These lipids play a crucial role in maintaining the structure and function of the cell membrane.

The membrane surround and protect the cell?

The membrane is composed of a lipid bilayer that surrounds the cell, providing a barrier between the internal and external environment. It controls the entry and exit of molecules, allowing the cell to maintain internal conditions necessary for survival. Additionally, the membrane contains proteins that play a role in cell communication, adhesion, and transport.


The main role for the cell membrane is to?

regulate the movement of substances in and out of the cell. It acts as a barrier, controlling the exchange of nutrients, waste products, and other molecules between the cell and its environment. Additionally, the cell membrane is involved in cell signaling and communication.


Membranous sac formed by the pinching off of pieces of cell membrane?

The membranous sac formed by pinching off pieces of cell membrane is known as a vesicle. Vesicles play a crucial role in transporting molecules within the cell and to and from the cell membrane. This process is called vesicular transport.
