Achievement objective LW 7-1

Students will:

  • explore the diverse ways in which animals and plants carry out life processes.


  • Compares and contrasts structures with similar function in organisms from different groups.
  • Relates differences in adaptations for the same life process across groups of organisms to the niche occupied by each group.
  • Explains how organ systems within an organism work together in a coordinated way.
  • Describes life processes at the cell level in terms of their inputs and outputs and the factors affecting them.
  • Recognises DNA replication and mitosis as stages in the cell cycle.
  • Relates structure of and organisation within a cell to how it enables cellular processes to proceed efficiently.
  • Compares the structure and internal organisation of different types of cells in terms of their specific functions.

Possible context elaborations

  • Organ systems in various organisms: using observation or dissection, compare their gas exchange adaptations.
  • How and why do pulse and breathing rates change with exercise?
  • A plant’s dilemma: Why do guard cells close when maximum sunlight is available for photosynthesis?
  • Why can’t I hold my breathe for very long?
  • Reaction time as an indicator of the coordination between nervous and skeletomuscular systems. How does tiredness affect my driving?
  • Microscopic examination and comparison of stomata in leaves of xerophytic and mesophytic plants.
  • Agar blocks as a model to explore the relationship between surface-area-to-volume ratio and the efficiency of diffusion.
  • Investigate how Tibetans and Andeans are differently adapted to high altitude living.
  • Why do the cells lining the small intestine have microvilli while cells lining the mouth do not?
  • How are stem cells different? How can we use them to improve health?

Assessment for qualifications

At the time of publication, achievement standards were in development to align them with The New Zealand Curriculum. Please ensure that you are using the correct version of the standards by going to the NZQA website.

The NZQA subject-specific resources pages are very helpful. From there, you can find all the achievement standards and links to assessment resources, both internal and external.

Aligned level 1 achievement standards were registered for use in 2011 and level 2 for use in 2012; level 3 will be registered for use in 2013.
