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






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






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






4. 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






5. 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






6. Having a daily cycle or occurring every day






7. A cue using the earths magnetic field






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






9. Derived or originating externally






10. Yearly activity period - approximately 360 days






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






12. First in order of importance






13. Having more than one spouse at a time






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






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






16. 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






17. Willing to submit without resistance to authority






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






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






20. Working together between species or in a species






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






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






23. Having only one spouse at a time






24. Orienting or directing homeward or to a destination






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






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






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






28. Plant hormone that stimulates fruit ripening and leaf drop






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






30. 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.






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






32. Cause responses that alter conditions in the internal environment






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






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






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






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






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






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






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






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






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






42. When one organism has power over another






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






44. 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






45. Derived or originating internally






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






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






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






49. Of or relating to or occurring in the night






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