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).
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 ...
A specialized layer of cytoplasmic proteins lining the inner face of the cell membrane in most eukaryotic cells, composed primarily of actin microfilaments and myosin motor proteins and usually 100–1000 nanometres thick, which functions as a modulator of membrane behavior and cell surface properties. cell counting
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.
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 ...
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.
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 membrane modules are complex structures, consisting of a number of different polymeric components and, potentially, the individual components can be recovered for other purposes. Plastic solid waste treatment and recycling can be separated into mechanical recycling, chemical recycling and energy recovery.
