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






2. Derived or originating externally






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






4. A cue using the earths magnetic field






5. Willing to submit without resistance to authority






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






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






8. Disposed to attack; militant; assertive; pushing






9. 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






10. 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






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






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






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






14. Having a daily cycle or occurring every day






15. Plant hormone that stimulates fruit ripening and leaf drop






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






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






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






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






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






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






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






23. Having more than one spouse at a time






24. 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






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






26. Orienting or directing homeward or to a destination






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






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






29. Cause responses that alter conditions in the internal environment






30. When one organism has power over another






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






32. Foe - opponent - adversary






33. Cessation from or slowing of activity during the winter






34. First in order of importance






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






36. Any area that an animal defends against other animals






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






38. Of or relating to or occurring in the night






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






40. 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






41. 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






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






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






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






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






46. 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.






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






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






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






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