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






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






3. 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






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






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






6. Having a daily cycle or occurring every day






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






8. Of or relating to or occurring in the night






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






10. 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






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






12. Any area that an animal defends against other animals






13. When one organism has power over another






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






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






16. Foe - opponent - adversary






17. First in order of importance






18. Derived or originating internally






19. Working together between species or in a species






20. 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.






21. Second in order of importance






22. Cause responses that alter conditions in the internal environment






23. 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






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






25. Cessation from or slowing of activity during the winter






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






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






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






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






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






31. 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






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






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






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






35. Derived or originating externally






36. Having only one spouse at a time






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






38. Plant hormone that stimulates fruit ripening and leaf drop






39. Orienting or directing homeward or to a destination






40. Having more than one spouse at a time






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






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






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






44. Yearly activity period - approximately 360 days






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






46. A cue using the earths magnetic field






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






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






49. Willing to submit without resistance to authority






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