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






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






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






4. Derived or originating externally






5. Plant hormone that stimulates fruit ripening and leaf drop






6. Willing to submit without resistance to authority






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






8. Having only one spouse at a time






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






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






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






12. Cause responses that alter conditions in the internal environment






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






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






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






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






17. Any area that an animal defends against other animals






18. Second in order of importance






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






20. Orienting or directing homeward or to a destination






21. 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






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






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






24. Having more than one spouse at a time






25. 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.






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






27. 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






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






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






30. Working together between species or in a species






31. 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






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






33. First in order of importance






34. Having a daily cycle or occurring every day






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






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






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






38. Foe - opponent - adversary






39. Cessation from or slowing of activity during the winter






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






41. A cue using the earths magnetic field






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






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. Having from birth; occurring naturally rather than being learned






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






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






47. Yearly activity period - approximately 360 days






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






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






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