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






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






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






4. Of or relating to or occurring in the night






5. 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






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. Cause responses that alter conditions in the internal environment






8. Working together between species or in a species






9. Orienting or directing homeward or to a destination






10. When one organism has power over another






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






12. 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






13. Yearly activity period - approximately 360 days






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






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






16. First in order of importance






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






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






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






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






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






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






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






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






25. Foe - opponent - adversary






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






27. Plant hormone that stimulates fruit ripening and leaf drop






28. Having more than one spouse at a time






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






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






31. 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






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






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






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






35. Disposed to attack; militant; assertive; pushing






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






37. A cue using the earths magnetic field






38. Second in order of importance






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






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






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






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






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






44. Having a daily cycle or occurring every day






45. 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.






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






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






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






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






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