Cell Membrane Structure And Function Quizlet
The nucleic acid may be single- or double-stranded.
Cell membrane structure and function quizlet. Isolate the cytoplasm from the external environment. Electron microscopic examinations of cell membranes have led to the development of the lipid bilayer model also referred to as the fluid-mosaic model. Most viruses have either RNA or DNA as their genetic material.
The cell membrane functions as a semi-permeable barrier allowing a very few molecules across it while fencing the majority of organically produced chemicals inside the cell. All cells are surrounded by a plasma membrane. The cell membranes four primary functions include cell signaling selective transport excretion of wastes and structural support.
The cell membrane is also known as plasma membrane or plasmalemma. Chapter 5 - Membrane Structure and Function. Start studying Cell Membrane Structure and Function.
The cell membrane plasma membrane is a thin semi-permeable membrane that surrounds the cytoplasm of a cell. Lipid-soluble molecules and some small molecules can permeate the membrane but the lipid bilayer effectively repels the. The plasma membrane and the membranes of the various organelles each have unique collections of proteins.
To protect the cell from its surroundingsIt also recognizes certain chemicals and molecules that can or cant go into the cell. Process in which one cell divides into two cells each of which is identical to the original cell. Allowing interaction with other cells and with the extracellular environment.
