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






2. Cause responses that alter conditions in the internal environment






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






4. Derived or originating externally






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






6. 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.






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






8. Plant hormone that stimulates fruit ripening and leaf drop






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






10. 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






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






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






13. Disposed to attack; militant; assertive; pushing






14. First in order of importance






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






16. Willing to submit without resistance to authority






17. Cessation from or slowing of activity during the winter






18. Yearly activity period - approximately 360 days






19. Working together between species or in a species






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






21. Having only one spouse at a time






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






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






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






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






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






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






28. Having a daily cycle or occurring every day






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






30. Second in order of importance






31. Derived or originating internally






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






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






34. 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






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






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






37. Orienting or directing homeward or to a destination






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






39. Of or relating to or occurring in the night






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






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






42. 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






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






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






45. 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






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






47. When one organism has power over another






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






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






50. Foe - opponent - adversary
