What substance helps hold the phospholipid layers of cell membrane together and reduce the visoity of the membrane?
Cholesterol is the substance that helps hold the phospholipid layers of the cell membrane together while also reducing the viscosity of the membrane. It intersperses between the phospholipid molecules, providing stability and fluidity, which is crucial for membrane functionality. By preventing the fatty acid chains of phospholipids from packing too closely, cholesterol enhances membrane flexibility, allowing for better movement of proteins and lipids within the membrane.
In both plant and animal cells what does the cell membrane do?
They protect and hold the cells together. It controles wht goes in and out of the cell.
What does a cell of a eukaryote to hold DNA that a cell of a prokaryote does not have?
cell membrane
What molecule compose the cell membrane?
A cellular membrane — including plasma membrane and internal membrane — is made of glycerophospholipids, molecules composed of glycerol, a phosphate group, and two fatty acid chains. Creative Biogene
What is the function of a plasma membrane cell?
The plasma membrane of a cell acts as a barrier, regulating the passage of substances in and out of the cell. It also helps maintain the cell's internal environment and communicates with other cells. Additionally, the plasma membrane contains receptors that allow the cell to respond to signals from its environment.
What hold the cytoplasm in a cell together?
cell membrane
What does the cell membrane in the animal cell do?
The function of the cell membrane is to hold the cell together and control what goes in and out of the cell.
What does cell membrane job is?
To hold the cell together. It acts as a barrier

What helps the cell hold its shape if it does not have a cell wall?
The cell has a lipid bilayer with embedded proteins that gives it shape. The cell membrane is rather fluid but also slightly rigid. This allows the cell to change shape but it cannot change shape very much. The membrane can seal itself if pierced by something very thin like a pin.The cell membrane holds it together as it's made of phospholipids.
What is the function of the cell membrane in a bacteria cell?
It hold every thing together and has the same function as a cell membrane that means, it is surrounding the cell and deciding what to let into the cell.
In both plant and animal cells the cell membrane what?
They protect and hold the cells together. It controles wht goes in and out of the cell.

What are two uses of carbohydrates within animals?
They hold phosphates in the phospholipid bilayer (cell membrane) together
What does the cell membrane do in plant and animal cells?
They protect and hold the cells together. It controles wht goes in and out of the cell.
What does a cell of a eukaryote to hold DNA that a cell of a prokaryote does not have?
cell membrane
What is the functrion of cell membrane?
it is a semi-permeable membrane that will allow small molecules to pass through it. its function is to control what passes through and also to hold the cells together
