Purpose
This unit standard is for people working in a horticulture
context.
People credited with this unit standard are able to demonstrate
understanding of plant structures and their functions; plant
tissue structures and their importance for plant growth; the
importance of plant processes for plant growth and/or
development; and the effects of environmental factors on plant
processes.

Explanatory notes
In the context of this unit standard, understanding means that there should be evidence of
a learner’s thorough comprehension of a topic. A learner with a good understanding of a
topic should have applied, or should be able to apply what they have learnt to a workplace
situation and will be able to alter their practices to the different contexts they are applying
their learning to. Assessors should be confident that the learner’s understanding is
embedded in their practices and behaviour.

Please note
Providers must be granted consent to assess against standards (accredited) by NZQA,
before they can report credits from assessment against unit standards or deliver courses
of study leading to that assessment.
Industry Training Organisations must be granted consent to assess against standards by
NZQA before they can register credits from assessment against unit standards.
Providers and Industry Training Organisations, which have been granted consent and
which are assessing against unit standards must engage with the moderation system that
applies to those standards.
Requirements for consent to assess and an outline of the moderation system that applies
to this standard are outlined in the Consent and Moderation Requirements (CMR). The
CMR also includes useful information about special requirements for organisations wishing
to develop education and training programmes, such as minimum qualifications for tutors
and assessors, and special resource requirements.
