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






2. Plant hormone that stimulates fruit ripening and leaf drop






3. 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






4. Derived or originating internally






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






6. Willing to submit without resistance to authority






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






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






9. Derived or originating externally






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






11. 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






12. Disposed to attack; militant; assertive; pushing






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






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






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






16. First in order of importance






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






18. Second in order of importance






19. Having more than one spouse at a time






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






21. Having only one spouse at a time






22. Working together between species or in a species






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






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






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






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






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






28. 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






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






30. Any area that an animal defends against other animals






31. Of or relating to or occurring in the night






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






33. Cessation from or slowing of activity during the winter






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






35. 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






36. A cue using the earths magnetic field






37. Foe - opponent - adversary






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






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






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






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






42. Having a daily cycle or occurring every day






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






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






45. 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






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






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






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






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






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