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 or occurring in the night






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






3. 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






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






5. When one organism has power over another






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






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






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






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






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






11. A cue using the earths magnetic field






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






13. Cessation from or slowing of activity during the winter






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






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






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






17. 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






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






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






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






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






22. Any area that an animal defends against other animals






23. Second in order of importance






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






25. Having only one spouse at a time






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






27. First in order of importance






28. 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.






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






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






31. Plant hormone that stimulates fruit ripening and leaf drop






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






33. Disposed to attack; militant; assertive; pushing






34. 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






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






36. Foe - opponent - adversary






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






38. Yearly activity period - approximately 360 days






39. Orienting or directing homeward or to a destination






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






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






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






43. 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






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






45. Working together between species or in a species






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






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






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






49. Derived or originating internally






50. Cause responses that alter conditions in the internal environment
