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. Any area that an animal defends against other animals






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






3. When one organism has power over another






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






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






6. 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






7. A cue using the earths magnetic field






8. Derived or originating externally






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






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






11. Second in order of importance






12. Orienting or directing homeward or to a destination






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






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






15. Plant that generally requires long nights-- 12 or more hours of darkness to begin the flowering process.






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






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






18. 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






19. Plant hormone that stimulates fruit ripening and leaf drop






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






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






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






23. When the amount of random turning is related to the intensity of a stimulus (unorientated response)






24. A biological clock that enables a migrating bird or insect to fly using the sun and continuously adjust its angle to the sun while flying.






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






26. Having more than one spouse at a time






27. Stimulates cell division and growth of lateral buds. Causes dormant seeds to sprout.






28. Substance produced in the tip of a seedling that stimulates cell elongation






29. Disposed to attack; militant; assertive; pushing






30. A hormone that promotes seed and bud germination - stem elongation - and leaf growth; stimulate flowering and development of fruit; affect root growth and differentiation






31. A plant hormone that brings about dormancy in buds - mantains dormancy in seeds - and brings about stomatal closing - among other effects.






32. Derived or originating internally






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






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






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






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






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






38. The resemblance of an animal species to another species or to natural objects






39. 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






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






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






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






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






44. 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






45. A group or system in which positions of power are ranked






46. First in order of importance






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






48. 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






49. A colored chemical compound that absorbs light - producing color






50. Cause responses that alter conditions in the internal environment
