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. 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.






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






3. When one organism has power over another






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






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






6. Second in order of importance






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






8. Working together between species or in a species






9. Orienting or directing homeward or to a destination






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






11. Plant hormone that stimulates fruit ripening and leaf drop






12. Having only one spouse at a time






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






14. 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






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






16. The process by which evolution selects for genes that cause individuals to provide benefits to their relatives






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






18. Cause responses that alter conditions in the internal environment






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






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






21. First in order of importance






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






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






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






25. 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






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






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






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






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






30. 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






31. Behaviors that have been developed by experience rather than by having them from birth






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






33. 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






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






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






36. Willing to submit without resistance to authority






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






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






39. A cue using the earths magnetic field






40. Having a daily cycle or occurring every day






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






42. Having more than one spouse at a time






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






44. Of or relating to or occurring in the night






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






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






47. Foe - opponent - adversary






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






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






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