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. 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






2. Any area that an animal defends against other animals






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






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






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






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






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






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






9. 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






10. When one organism has power over another






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






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






13. 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






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






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






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






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






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






19. Cessation from or slowing of activity during the winter






20. Foe - opponent - adversary






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






22. Plant hormone that stimulates fruit ripening and leaf drop






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






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






25. Working together between species or in a species






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






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






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






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






30. First in order of importance






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






32. Orienting or directing homeward or to a destination






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






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






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






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






37. 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






38. Yearly activity period - approximately 360 days






39. 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.






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






41. Having a daily cycle or occurring every day






42. 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






43. Derived or originating externally






44. Cause responses that alter conditions in the internal environment






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






46. Second in order of importance






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






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






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






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