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 polygamous mating system involving one female and many males






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






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






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






5. 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






6. 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






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






8. 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






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






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






11. Plant hormone that stimulates fruit ripening and leaf drop






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






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






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






15. Having a daily cycle or occurring every day






16. Willing to submit without resistance to authority






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






18. Second in order of importance






19. 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






20. Disposed to attack; militant; assertive; pushing






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






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






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






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






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






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






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






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






29. Cessation from or slowing of activity during the winter






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






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






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






33. Yearly activity period - approximately 360 days






34. When one organism has power over another






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






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






37. Cause responses that alter conditions in the internal environment






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






39. A cue using the earths magnetic field






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






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






42. Of or relating to or occurring in the night






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






44. Having more than one spouse at a time






45. Derived or originating internally






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






47. Foe - opponent - adversary






48. Orienting or directing homeward or to a destination






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






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