Basically the same as antibiosis, except that the definition emphasises the chemical connection 2 of 19 Dormancy when seeds will not germinate unless certain conditions happen. (Cutting off the coat or long periods of cold) 3 of 19 Endogenous Internal rhythm that occurs when there are no external cues. It is caused by a biological clock 4 of 19 Exogenous Rhythm that continues only when external cues are present 5 of 19 Antibiosis Interspecific relationship where one organism is harmed, but the other is unaffected 6 of 19 Batesian mimicry A harmless animal that looks like a poisonous one. 7 of 19 Ambivalence When a gesture contains both dominance and submission 8 of 19 Entrainment Forcing the free running period to follow an external pattern. 9 of 19 Interspecific Between two different species 10 of 19 Intraspecifc Within one species 11 of 19 Kinesis A whole body response of animals where the response is independant of the stimulus direction, but may depend on the intensity of the stimulus. 12 of 19 Mullerian mimicry Several poisonous species have similar colourations 13 of 19 Nastic movement A plant response that is independent of the direction of stimulus. It is not a growth response, usually involves turgor (cell water) pressure. 14 of 19 photoperiodism response of plants to lengths of day(or night) 15 of 19 Phytochrome PLant pigment that controls the photoperiodic response. 16 of 19 Taxis Movement of an animal or part of its body towards or away from a directional stimulus 17 of 19 Tropism a plant growth response to a directional stimulus 18 of 19 Vernalisation Exposure of seeds to a period of cold to break seeds' dormancy 19 of 19
