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. Orienting or directing homeward or to a destination






2. Cause responses that alter conditions in the internal environment






3. First in order of importance






4. Working together between species or in a species






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






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






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






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






9. Derived or originating externally






10. Of or relating to or occurring in the night






11. Cessation from or slowing of activity during the winter






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






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






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






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






16. Having a daily cycle or occurring every day






17. Foe - opponent - adversary






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






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






20. 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






21. Any area that an animal defends against other animals






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






23. 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






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






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






26. Having more than one spouse at a time






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






28. 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.






29. Plant hormone that stimulates fruit ripening and leaf drop






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






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






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






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






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






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






36. Having only one spouse at a time






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






38. Yearly activity period - approximately 360 days






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






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






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






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






43. Second in order of importance






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






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






46. When one organism has power over another






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






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






49. A cue using the earths magnetic field






50. Derived or originating internally
