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. 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.






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






3. Derived or originating internally






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






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






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






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






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






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






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






11. Willing to submit without resistance to authority






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






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






14. Yearly activity period - approximately 360 days






15. Derived or originating externally






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






17. Working together between species or in a species






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






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






20. A cue using the earths magnetic field






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






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






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






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






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






26. Orienting or directing homeward or to a destination






27. Any area that an animal defends against other animals






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






29. 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






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






31. Cessation from or slowing of activity during the winter






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






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






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






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






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






37. Second in order of importance






38. 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






39. 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






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






41. First in order of importance






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






43. Disposed to attack; militant; assertive; pushing






44. Having only one spouse at a time






45. When one organism has power over another






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






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






48. Of or relating to or occurring in the night






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






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