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 a daily cycle or occurring every day






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






3. Foe - opponent - adversary






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






5. Reversible growth or turgor movement in response to a non directional stimulus






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






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






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






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






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






11. Having only one spouse at a time






12. Any area that an animal defends against other animals






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






14. Having more than one spouse at a time






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






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






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






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






19. Plant hormone that stimulates fruit ripening and leaf drop






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






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






22. 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






23. Disposed to attack; militant; assertive; pushing






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






25. Cause responses that alter conditions in the internal environment






26. Working together between species or in a species






27. Second in order of importance






28. Orienting or directing homeward or to a destination






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






30. A cue using the earths magnetic field






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






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






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






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






35. 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






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






37. Derived or originating externally






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






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






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






41. Yearly activity period - approximately 360 days






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






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






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






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






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






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. 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.






49. 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






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