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. Having only one spouse at a time






2. Second in order of importance






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






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






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






6. Having a daily cycle or occurring every day






7. Derived or originating internally






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






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






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






11. Derived or originating externally






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






13. Cause responses that alter conditions in the internal environment






14. Plant hormone that stimulates fruit ripening and leaf drop






15. Orienting or directing homeward or to a destination






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






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






19. Cessation from or slowing of activity during the winter






20. 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.






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






22. Willing to submit without resistance to authority






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






24. A cue using the earths magnetic field






25. Any area that an animal defends against other animals






26. 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






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






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






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






30. Of or relating to or occurring in the night






31. Working together between species or in a species






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






33. 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






34. Disposed to attack; militant; assertive; pushing






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






36. Foe - opponent - adversary






37. 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






38. When one organism has power over another






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






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






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






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






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






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






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






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






47. Yearly activity period - approximately 360 days






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






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






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