What is another name for the cell membrane generally speaking?
The cell membrane is also called the PLASMA membrane and is made of a phospholipid BI-LAYER. The phospholipids have a hydrophilic (water attracting) HEADS and two hydrophobic (water repelling) TAILS. The head of a phospholipid is made of an alcohol and GLYCEROL group, while the tails are chains of FATTY ACIDS.
What is cell also known as?
The cell (from the Latin word ‘cellula’ meaning “small room”) is the basic structural and functional unit of life forms. Every cell consists of a cytoplasm enclosed within a membrane, which contains many biomolecules such as proteins and nucleic acids.
What is another name for the cell membrane quizlet?
Plasma Membrane. It is made of a phospholipid bilayer, it protects/encloses/and controls the transportation of materials in and out of the cell.
Why is cell membrane called plasma membrane?
The cell contains a protoplasm (or simply plasm), which is the semi-fluid living matter. This living matter or plasm is contained inside a biological membrane referred to as the plasma membrane. Because it surrounds the entire cell, this plasma membrane is specifically referred to as the cell membrane.
What is cell membrane made of?
With few exceptions, cellular membranes — including plasma membranes and internal membranes — are made of glycerophospholipids, molecules composed of glycerol, a phosphate group, and two fatty acid chains. Glycerol is a three-carbon molecule that functions as the backbone of these membrane lipids.
What makes up the bilayer?
A bilayer is composed of two sheets of phospholipid molecules with all of the molecules of each sheet aligned in the same direction.
Is cell also known as plasma?
A plasma cell is a type of white blood cell. Also called plasmacyte.
Why is cell membrane called semipermeable?
Why is cell membrane called a selectively permeable membrane? It is permeable only during certain stage of the cell division. It allows only selective molecules to pass through it. It allows only water to pass.
Why is cell membrane also called plasma membrane?
Is plasma membrane and cell membrane the same thing? Yes, the plasma membrane and cell membrane are the same. Both refer to the biological membrane which separates the interior of the cell from the cell’s extracellular space.
