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. Disposed to attack; militant; assertive; pushing






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






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






5. 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.






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






7. Having only one spouse at a time






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






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






10. Any area that an animal defends against other animals






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






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






13. Yearly activity period - approximately 360 days






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






15. Derived or originating externally






16. When one organism has power over another






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






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






19. Plant hormone that stimulates fruit ripening and leaf drop






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






21. 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






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






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






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






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






26. 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






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






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






29. 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






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






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






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






33. Second in order of importance






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






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






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






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






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






39. Cause responses that alter conditions in the internal environment






40. A cue using the earths magnetic field






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






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






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






44. Willing to submit without resistance to authority






45. 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






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






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






48. Having a daily cycle or occurring every day






49. Having more than one spouse at a time






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