The primary structure is a lipid bilayer. The cell membrane is a fine structure that envelops a cell, separating the content of the cell from its surroundings. It regulates the substances that can enter and leave the cell. The cell membrane surrounds the cell and protects the cell, communicates with other cells, and controls what enters and exits the cell.The cell membrane is m Cell Defense: The Plasma Membrane.

a cell that contains a nucleus and membrane bound organelles. prokaryotes. Protein characteristic of the postsynaptic membrane. In a chemical synapse, the postsynaptic membrane is the membrane that receives a signal (binds neurotransmitter) from the presynaptic cell and responds via depolarisation or hyperpolarisation. Since there are no membrane-bound organelles in prokaryotes, the ribosomes float free in the cytosol.

2018-02-18 · Animal Cell Definition: Animal cells, which are the fundamental units of life in the Animal Kingdom, are eukaryotic cells. This means that they contain a true (membrane-bound nucleus) along with other membrane-bound organelles. All these work together to perform specific functions that are needed for the proper functioning of the cell. In a chemical synapse, the presynaptic membrane is the cell membrane of an axon terminal that faces the receiving cell. The postsynaptic membrane is separated from the presynaptic membrane by the synaptic cleft. Mitochondria are energy-producing organelles found in most living cells.
