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 a non-directional response to a stimulus or a change in activity rate in response to a change in the intensity of the stimulus






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






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






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






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






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






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






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






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






10. Disposed to attack; militant; assertive; pushing






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






12. 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






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






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






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






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






17. 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






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






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






20. Cause responses that alter conditions in the internal environment






21. 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






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






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






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






25. Any area that an animal defends against other animals






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






27. A cue using the earths magnetic field






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






29. When one organism has power over another






30. Plant hormone that stimulates fruit ripening and leaf drop






31. First in order of importance






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






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






34. Foe - opponent - adversary






35. 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






36. Second in order of importance






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






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






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






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






41. Yearly activity period - approximately 360 days






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






43. 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.






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






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






46. Of or relating to or occurring in the night






47. Cessation from or slowing of activity during the winter






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






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






50. Having more than one spouse at a time
