NCEA Level 3: Animal Plant Responses

Subject : NCEA
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. When the amount of random turning is related to the intensity of a stimulus (unorientated response)






2. Having from birth; occurring naturally rather than being learned






3. First in order of importance






4. Having only one spouse at a time






5. A change in an organism's surroundings that causes the organism to react.






6. Having more than one spouse at a time






7. Serves as a navigational cue. Many birds use star patterns and movement for navigation.






8. The environmental agent that resets the biological clock e.g: change in light - temperature






9. When an animal is active around sunrise and sunset.






10. Derived or originating externally






11. Period of dormancy - usually seasonal - which growth and development cease and metabolism is greatly reduced






12. An innate mechanism in living organisms that controls the periodicity of many physiological functions






13. Period of time during which a plant embryo is alive but not growing






14. Located in the brain; secretes hormone melatonin; in some species - it regulates the biological clock and biorhythms






15. Movement of the whole organism towards or away from a stimulus coming from one direction






16. When organisms orient themselves either towards or away from a stimulus






17. Mating behaviour in which a number of males and females mates with each other.






18. Having a daily cycle or occurring every day






19. This is the growth towards or away from a stimulus coming from one direction. If the movement is towards the stimulus it is positive - if it is away from the stimulus it is negative






20. Derived or originating internally






21. Plant hormone that stimulates fruit ripening and leaf drop






22. The natural period of the rhythm if there are no external cues.






23. A cue using the earths magnetic field






24. Foe - opponent - adversary






25. Any area that an animal defends against other animals






26. Type of behavior in which an animal sends out stimuli—such as sounds - visual displays - or chemicals—in order to attract a member of the opposite sex






27. Special structures that allow living organisms to sense the conditions of their internal or external environment






28. A special case of polymorphism based on the distinction between the secondary sex characteristics of males and females.






29. Aggressive or defensive social behavior (fighting - fleeing - submitting) between individuals of the same species






30. A polygamous mating system involving one male and many females






31. Diagram showing the periods of activity and rest of an organism over a number of twenty four hour periods so that trends in activity can be identified






32. This is a non-directional response to a stimulus or a change in activity rate in response to a change in the intensity of the stimulus






33. The period of daylight - specific for any given species - that triggers a long-day or a short-day response in organisms






34. Reversible growth or turgor movement in response to a non directional stimulus






35. Cause responses that alter conditions in the internal environment






36. A polygamous mating system involving one female and many males






37. To change the start times of a rhythm - but not its period






38. Plant that generally requires short nights-- less that 10-12 hours of darkness to begin the flowering process.






39. Of or relating to or occurring in the night






40. Second in order of importance






41. Of or relating to biological processes occurring at 24-hour intervals






42. Chemical messengers that are manufactured by the endocrine glands - travel through the bloodstream - and affect other tissues






43. Light receptor pigment in photoperiodism. Pr (red-light absorbing) vs Pfr (infrared light absorbing) In short-day plants - it stops flowering but in long-day plants it induces flowering






44. The periodic passage of groups of animals (especially birds or fishes) from one region to another for feeding or breeding






45. The lobes of the brain that receive signals from the receptors in the eyes






46. Prolonged relationship between male and female - associated with joint parental care






47. When one organism has power over another






48. A single receptor is used to calculate the direction of a stimulus






49. Disposed to attack; militant; assertive; pushing






50. Cessation from or slowing of activity during the winter
