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






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






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






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






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






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






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






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






9. Cause responses that alter conditions in the internal environment






10. Derived or originating internally






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






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. Any area that an animal defends against other animals






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






15. 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






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






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






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






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






20. Cessation from or slowing of activity during the winter






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






22. When one organism has power over another






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






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






25. First in order of importance






26. 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






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






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






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






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






31. Having only one spouse at a time






32. Having more than one spouse at a time






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






34. Plant hormone that stimulates fruit ripening and leaf drop






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






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






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






38. Disposed to attack; militant; assertive; pushing






39. Derived or originating externally






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






41. Working together between species or in a species






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






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






44. Foe - opponent - adversary






45. Orienting or directing homeward or to a destination






46. Yearly activity period - approximately 360 days






47. 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






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






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






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