Illustration of a eukaryotic cell membrane Comparison of a eukaryotic vs. a prokaryotic cell membrane. The cell membrane (also known as the plasma membrane or cytoplasmic membrane, and historically referred to as the plasmalemma) is a biological membrane that separates and protects the interior of a cell from the outside environment (the extracellular space).
Cross-sectional diagram of a typical eukaryotic cell membrane cell physiology The study of the various biological activities and biochemical processes which sustain life inside cells, particularly (but not necessarily limited to) those related to metabolism and energy transfer, growth and reproduction, and the ordinary processes of the cell cycle.
Cross-sectional view of the structures that can be formed by phospholipids in an aqueous solution. A biological membrane, biomembrane or cell membrane is a selectively permeable membrane that separates the interior of a cell from the external environment or creates intracellular compartments by serving as a boundary between one part of the cell and another.
Glycoproteins on the membrane assist the cell in recognizing other cells, in order to exchange metabolites and form tissues. Other proteins on the plasma membrane allow attachment to the cytoskeleton and extracellular matrix; a function that maintains cell shape and fixes the location of membrane proteins. Enzymes that catalyze reactions are ...
An irregularly shaped region within a prokaryotic cell which contains most or all of the cell's genetic material, but is not enclosed by a nuclear membrane as in eukaryotes. nucleolin The primary protein of which the eukaryotic nucleolus is composed, thought to play important roles in chromatin decondensation, transcription of ribosomal RNA ...
Detailed diagram of lipid bilayer of cell membrane. The cell membrane, or plasma membrane, is a selectively permeable [citation needed] biological membrane that surrounds the cytoplasm of a cell. In animals, the plasma membrane is the outer boundary of the cell, while in plants and prokaryotes it is usually covered by a cell wall.
Cell cycles are essential processes in all unicellular and multicellular organisms. cell division Any process by which a parent cell divides into two or more daughter cells. Examples include binary fission, mitosis, and meiosis. cell membrane The semipermeable membrane surrounding the cytoplasm of a cell. cell nucleus The "control room" for the ...
The cell membrane, also called the plasma membrane or plasmalemma, is a semipermeable lipid bilayer common to all living cells.
