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






2. Cessation from or slowing of activity during the winter






3. 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






4. 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






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






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






7. First in order of importance






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






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






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






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






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






13. 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






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






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






16. Orienting or directing homeward or to a destination






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






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






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






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






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






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






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






24. Having only one spouse at a time






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






26. Plant hormone that stimulates fruit ripening and leaf drop






27. 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






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






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






30. A cue using the earths magnetic field






31. Cause responses that alter conditions in the internal environment






32. Having more than one spouse at a time






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






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






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






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






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






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






39. Working together between species or in a species






40. When one organism has power over another






41. Having a daily cycle or occurring every day






42. Derived or originating internally






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






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






45. Foe - opponent - adversary






46. Yearly activity period - approximately 360 days






47. Of or relating to or occurring in the night






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






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






50. 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
