NCEA Level 3: Animal Plant Responses

Subject : NCEA
  • 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 internally

2. 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

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

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

5. When one organism has power over another

6. Willing to submit without resistance to authority

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

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

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

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

11. 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

12. 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.

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

14. Plant hormone that stimulates fruit ripening and leaf drop

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

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

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

18. 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

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

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

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

22. Second in order of importance

23. Orienting or directing homeward or to a destination

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

25. 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

26. Having more than one spouse at a time

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

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

29. Having a daily cycle or occurring every day

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

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

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

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

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

35. 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

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

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

38. Cause responses that alter conditions in the internal environment

39. Foe - opponent - adversary

40. A cue using the earths magnetic field

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

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

43. Working together between species or in a species

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

45. Yearly activity period - approximately 360 days

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

47. Derived or originating externally

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

49. Having only one spouse at a time

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