Cell Membranes
We have been talking about cells being a unit of organization in biology. Let's look at the cell membrane and see how that membrane keeps all of the pieces inside.
Cell Membrane (Plasma Membrane)
The cell membrane, also called the plasma membrane, is found in all cells and separates the interior of the cell from the outside environment. The cell membrane consists of a lipid bilayer that is semipermeable.
cell membrane - the part of the cell which separates the external environment from the cytoplasm; cell membranes have hydrophilic external surfaces and hydrophobic interiors.
cell membrane -- The outer membrane of a cell, which separates it from the environment. Also called a plasma membrane or plasmalemma.

Cell Membrane (also known as plasma membrane or plasmalemma) is surrounds all cells. It: 1) separates the inner parts of the cell from the outer environment; and 2) acts as a selectively permeable barrier to allow certain chemicals, namely water, ...
cell membrane
the outer boundary of cells, the structure of which is visible only under the electron microscope.
Cell membranes act as barriers to most, but not all, molecules. Development of a cell membrane that could allow some materials to pass while constraining the movement of other molecules was a major step in the evolution of the cell.
Cell Membrane: Every cell is enclosed in a membrane, a double layer of phospholipids (lipid bilayer).

plasmalemma The cell membrane.
plasmid A small circle of DNA that may be carried by a bacterium in addition to its genomic DNA.
plasmodesma A cytoplasmic strand that connects adjacent plant cells through pores in the cell wall.
Cells - What Is A Cell Membrane?
Found in both plant and animal cells, the cell membrane is the outside wall of a cell. In plant cells, it is a second wall, and is found just inside the main cell wall.
A method for transforrning DNA, especially useful for plant cells, in which high voltage pulses of electricity are used to open pores in cell membranes, through which foreign DNA can pass. Encapsidation.
A human cell is made up a central nucleus (containing DNA) a cytoplasm and a outer cell membrane.
Centimorgan (cM) A unit of measure of recombination frequency.
(Some animal viruses take along a portion of the cell membrane when they leave your cells, too.) Some of the viral proteins attach to protein receptors in your cell membranes. Viral proteins are recognized as foreign by your immune system.
Pericellular proteolysis represents one of the key modes by which the cell can modulate its environment, involving not only turnover of the extracellular matrix but also the regulation of cell membrane proteins, ...
Channel proteins that span the cell membrane form the ion channels. To determine the structure of proteins, scientists have often used X-ray crystallography.
Somewhat cylindrical in shape, plasmodesmata are lined with the plasma membrane so all connected cells are united through essentially one continuous cell membrane.
Integrins are proteins found in cell membranes that control many cellular processes and also serve as a channel through which viruses can enter and infect cells.
The string is the cell membrane, the pipe cleaners are the chromatids and the chalk is used to draw the spindle fibers and nuclear membrane, and the pinwheel macaroni is used to demonstrate centrioles(many different things can be used for this).
Proteins associated with the cell membranes of animal cells may bind to proteins of adjacent cells.
Permeases are enzymes that transport substances across the cell membrane, whether forward or outward the cell and they are highly specialized in their function. Besides, cell membranes operate as containers and as a protection for the cytoplasm.
G protein A protein located on the inside of the cell membrane that helps transmit molecular signals into cells.
Gene A unit of heredity; a segment of DNA that contains the code for making a specific protein or RNA molecule.
Septum
The growth of the cell membrane and wall between opposite ends of a growing cell, ultimately separating the cell into two daughter cells.
A process using high-voltage current to make cell membranes permeable to allow the introduction of new DNA; commonly used in recombinant DNA technology.
