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. 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






2. Plant hormone that stimulates fruit ripening and leaf drop






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






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






5. Foe - opponent - adversary






6. A cue using the earths magnetic field






7. 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






8. Derived or originating internally






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






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






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






12. Derived or originating externally






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






14. 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






15. Any area that an animal defends against other animals






16. Cause responses that alter conditions in the internal environment






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






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






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






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






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






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






23. When one organism has power over another






24. 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.






25. Disposed to attack; militant; assertive; pushing






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






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






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






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






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






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






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






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






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






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






36. Having more than one spouse at a time






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






38. 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






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






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






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






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






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






44. Of or relating to or occurring in the night






45. Having a daily cycle or occurring every day






46. Having only one spouse at a time






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






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






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






50. Orienting or directing homeward or to a destination
