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. Cessation from or slowing of activity during the winter






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






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






4. Orienting or directing homeward or to a destination






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






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






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






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






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






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






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






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






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






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






16. 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






17. 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






18. 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.






19. Having a daily cycle or occurring every day






20. Willing to submit without resistance to authority






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






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






23. Disposed to attack; militant; assertive; pushing






24. Having more than one spouse at a time






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






26. Working together between species or in a species






27. First in order of importance






28. Plant hormone that stimulates fruit ripening and leaf drop






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






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






31. Of or relating to or occurring in the night






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






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






34. 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






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






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






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






38. Derived or originating externally






39. Having only one spouse at a time






40. Second in order of importance






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






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






43. Yearly activity period - approximately 360 days






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






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






46. Any area that an animal defends against other animals






47. Foe - opponent - adversary






48. A cue using the earths magnetic field






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






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