The Action Potential An action potential‚ also called a spike‚ nerve impulse‚ and discharge‚ is the rapid reversal of charge of the cell membrane. These changes in charge occur within milliseconds‚ meaning the action potential travels very quickly down the axon in order to convey information over long distances. This transfer of information occurs within six phases and requires the presence of multiple pumps and channels embedded in the membrane to control ion concentration. Phase 1: The Resting

Water Transport The movement of plants from water to land has necessitated the development of internal mechanisms to supply all the parts of the plant with water. As discussed in Plant Classification‚ Vasular Tissues ‚ tracheophytes (including virtually all terrestrial plants except for mosses and liverworts)‚ have developed complex vascular systems that move nutrients and water throughout the plant body through "tubes" of conductive cells.
