A cell membrane consists of a phospholipid bilayer. A lipid is a fatty organic compound in our body. The cell membrane is a double layer of these lipids. Each phospholipid is made up of a head (containing phosphate) and two tails(containing fatty acids). The head is polar and hydrophilic, or interacts with water molecules. The tails are nonpolar and hydrophobic, which means that they do not interact with water molecules. The polar heads of the lipids cluster together on the outer part of the layers while the nonpolar tails cluster in the center of the two layers. Polar means that it has a charge.

What is the most basic component of the cell membrane?
phospholipids
Most membrane functions are carried out by which component of the membrane?
Most membrane functions are carried out by proteins. The cell membrane is important because it protects what is inside the cell from outside damage.
What component of the plasma membrane forms most of the cell's outer boundary?
the phospholipids. by weight it is half protein and half lipid
What is the thin outer boundary of an animal cell?
The cell membrane. It is a lipid bilayer with proteins integrated into it for transportation into and out of the cell.
What is the protective barrier of a cell?
Either the cell membrane, or the cell wall. The cell membrane is most common in animals, and protists, whereas some monerans, and most plants and fungi have a cell wall.
Which component of the cell is most directly involved in maintaining the cell's homeostasis?
the outer membrane
What is the most basic component of the cell membrane?
phospholipids
Most membrane functions are carried out by which component of the membrane?
Most membrane functions are carried out by proteins. The cell membrane is important because it protects what is inside the cell from outside damage.
Which biochemical would most likely be found as a component of a cell membrane?
hormones
What macromolecule is the main component of a cell membrane?
For most eukaryotic organisms it is dipalitoylphosphatidylcholine (DPPC), a phospholipid.
What component of the plasma membrane forms most of the cell's outer boundary?
the phospholipids. by weight it is half protein and half lipid
What part of the cell control most of the cell's activity?
The major part of the cell is controlled by the nucleus but the materials that come and go in the cell is the cell membrane.
The cell part that controls most of the cells activities is what?
The major part of the cell is controlled by the nucleus but the materials that come and go in the cell is the cell membrane.

How I can use cell membrane in a sentences?
cell membrane is the most outer part of a cell. cell membrane is very big in surface.
What is the protective barrier of a cell?
Either the cell membrane, or the cell wall. The cell membrane is most common in animals, and protists, whereas some monerans, and most plants and fungi have a cell wall.
