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 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






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






3. 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






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






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






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






7. 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.






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






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






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






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






12. When one organism has power over another






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






14. Plant hormone that stimulates fruit ripening and leaf drop






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






17. Cessation from or slowing of activity during the winter






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






19. Derived or originating externally






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






21. Yearly activity period - approximately 360 days






22. Having a daily cycle or occurring every day






23. Willing to submit without resistance to authority






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






25. Having only one spouse at a time






26. First in order of importance






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






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






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






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






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






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






33. Derived or originating internally






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






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






36. Disposed to attack; militant; assertive; pushing






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






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






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






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






41. Any area that an animal defends against other animals






42. Second in order of importance






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






44. Having more than one spouse at a time






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






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






47. Foe - opponent - adversary






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






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






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