I.         Chemical Control in Plants

characteristics of plant hormones

hormones

                                    auxins

                                                phototropism, geotropism (gravitropism), inhibition of lateral buds

                                                fruit development

III.       Nervous System General

                        Central Nervous System / Peripheral Nervous System
                                    Neurons
                                            multipolar, bipolar, unipolar
                                    Neuroglial Cells
                                            Central Nervous System

IV.        Action Potential

                        Electrochemical impulse
                        Chemical and Voltage gated channels
                        Synaptic Transmission 
                                Excitory post synaptic potential / Inhibitory post synaptic potential
