A

 
   
abaxial
   cf. adaxial
  underside of a leaf, facing away from the stem.
actinomorphic
   cf. zygomorphic
  radially symmetric flowers
action potential   an electrical pulse (with a duration of 1ms or so) that travels along the cell membrane, transmitting a signal from one cell to another, to coordinate some activities. The nervous system of animals use action potentials for communication between neurons and to transmit information to other tissues. Many plants generate action potentials also. In plants, the generation of an action potential is associated with the flow of potassium (K+) and calcium (Ca++), while in animals the flow of potassium (K+) and sodium (Na+) are used. An action potential  is caused by positive ions moving in and out of a particular cell.....
