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. Derived or originating externally






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






3. Cessation from or slowing of activity during the winter






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. Yearly activity period - approximately 360 days






6. Derived or originating internally






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






8. 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






9. 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






10. Having more than one spouse at a time






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






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






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






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






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






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






17. Working together between species or in a species






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






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






20. Disposed to attack; militant; assertive; pushing






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






22. Orienting or directing homeward or to a destination






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






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






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






26. A cue using the earths magnetic field






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






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






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






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






31. 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






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






33. Foe - opponent - adversary






34. Having only one spouse at a time






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






36. When one organism has power over another






37. First in order of importance






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






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






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






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






42. Cause responses that alter conditions in the internal environment






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






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






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






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






47. Plant hormone that stimulates fruit ripening and leaf drop






48. Having a daily cycle or occurring every day






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






50. 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.
