What else can I help you with?
Which type of membrane surrounds a cell?
this is the cell membrane made primarily of lipid molecules with proteins incorporated into it that aid in transport of molecules across the membrane
Is protoplasm made of the cell membrane?
The cell membrane is made of carbohydrate, lipid, and protein molecules.
What are the special doorways in the cell membrane made of?
Special doorways in the cell membrane are made of proteins called ion channels or transporters. These proteins allow specific ions or molecules to pass through the cell membrane, regulating the movement of substances in and out of the cell.
What would happen to a cell if the cell membrane was made of a molecule that did not repel water?
If the cell membrane was made of a molecule that did not repel water, the membrane would become permeable to water and other water-soluble molecules. This would disrupt the cell's ability to maintain internal conditions necessary for its normal functioning, potentially causing the cell to swell and burst due to osmotic imbalance.
What would happend if the fatty acids in a cell membrane were polar molecules?
The cell breaks open, because the cell membrane is made of a phospholipid bilayer
What is the cell made of?
The cell membrane is made of carbohydrate, lipid, and protein molecules.
What makes up the membrane of a cell?
The cell membrane is primarily composed of lipids such as phospholipids, cholesterol, and glycolipids. These lipids form a lipid bilayer that surrounds the cell, providing structure and regulating the movement of molecules in and out of the cell. Proteins are also embedded in the membrane, serving various functions such as transport, signaling, and structural support.

What organelle involved the processes of osmosis an diffusion?
Osmosis and diffusion take place across the plasma membrane, the outer "wall" of the cell. It is considered to be an organelle because it carries out a variety of functions. The cell membrane or plasma membrane is made up of a double layes of phosphorous and lipid molecules, known as the 'phospholipid bilayer'.

What can you conclude about the cell membrane structure if liquid soluble molecules move across the membrane?
It can be concluded that if the liquid soluble molecules move more readily across the membrane then the membrane must be made of lipids. When two parts are made of similar material then they will be more likely to allow other particles like them to pass.
Why can only molecules that are fat soluable permate a cell membrane?
The cell wall itself is made of lipid. To be more precise, the cell membrane is made of a bilayer of phospholipids. The hydrophobic fatty acid tails prevent water-soluble molecules passing through, but allow the transport of lipid-soluble molecules.
What would happen to a cell if the cell membrane was made if a molecule that did not repel water?
it would not keep working to do its functions
Why can hydrophobic molecules cross the membrane?
Hydrophobic molecules can cross the cell membrane because the membrane is made up of a double layer of lipids, which are also hydrophobic. This allows hydrophobic molecules to pass through the membrane easily, while hydrophilic molecules have a harder time crossing.
