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 group or system in which positions of power are ranked






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






3. Foe - opponent - adversary






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






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






6. Derived or originating externally






7. 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






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






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






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






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






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






13. 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.






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






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






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






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






18. Plant hormone that stimulates fruit ripening and leaf drop






19. When one organism has power over another






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






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






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






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






24. Having only one spouse at a time






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






26. Orienting or directing homeward or to a destination






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






28. 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






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






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






31. Having more than one spouse at a time






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






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






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






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






36. Having a daily cycle or occurring every day






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






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






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






40. Willing to submit without resistance to authority






41. Second in order of importance






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






43. Derived or originating internally






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






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






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






47. 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






48. A cue using the earths magnetic field






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






50. Of or relating to or occurring in the night
