Rationale

The aims of this course are to relate the structure of whole plants and their tissues to their known functions and to explore a selection of the major physiological processes which occur during plant growth and development and their interaction with the external environment.

Synopsis

The course is designed to inform a broad spectrum of students in plant science, wine science, biotechnology, ecology and education. The course examines essential processes in the life of plants: water uptake and transpiration; the nutrient requirements of plants; the effects of nutrient deficiencies; the transport of salts, sugars and other biomolecules within the plant; cell growth and development; the roles of plant hormones and the strategies adopted by plants to withstand environmental stresses.

This course contains a highly recommended residential school for both external and on-campus students (non-attendance will mean the student misses both an element for assessment preparation and an element of assessment).

Objectives

On completion of this course students will be able to:

  1. demonstrate an understanding of how the different tissues and organs enable the plant to function as an integrated system, responsive to the interaction of internal and environmental processes;
  2. demonstrate an understanding of the basic principles governing plant cell growth and the role of individual cell growth and development within the organism;
  3. demonstrate an understanding of the effects of major environmental stresses on normal plant functioning and the anatomical and physiological adaptations plants have evolved to tolerate these external factors;
  4. show skills in experimentation with plants in the laboratory and glasshouse;
  5. show improved skills in the written communication of scientific knowledge.

  2. Examiner to advise the due date of assignment 2.
  3. Examiner to advise the due date of Practical Report A. The Residential School is highly recommended as the data collected is used in the completion of Practical reports A and B. The dates of the residential school are available from the Residential School Timetable (http://www.usq.edu.au/handbook/current/resschoolsched.html).
  4. Examiner to advise the due date of Practical Report B. The Residential School is highly recommended as the data collected is used in the completion of Practical reports A and B. The dates of the residential school are available from the Residential School Timetable (http://www.usq.edu.au/handbook/current/resschoolsched.html).
  5. This will be a restricted examination covering all modules. The total working time for the examination is 2 hours. The examination date will be available via UConnect when the official examination timetable has been released.

Important assessment information

  1. Attendance requirements:
    Both external and on-campus students are highly recommended to attend the residential school as the residential school is linked to an assessment or an element of assessment preparation. It is the students' responsibility to attend and participate appropriately in all activities (such as the Residential School and tutorials (on-campus students)) scheduled for them, and to study all material provided to them or required to be accessed by them to maximise their chance of meeting the objectives of the course and to be informed of course-related activities and administration.

  2. Requirements for students to complete each assessment item satisfactorily:
    To complete the assignment satisfactorily, students must obtain at least 50% of the marks available for the assignment. To complete the examination satisfactorily, students must obtain at least 50% of the marks available for the examination. To complete the practical component satisfactorily, students must submit all practical reports and obtain at least 50% of the marks available.

  3. Penalties for late submission of required work:
    Students should refer to the Assessment Procedure http://policy.usq.edu.au/documents.php?id=14749PL (point 4.2.4)

  4. Requirements for student to be awarded a passing grade in the course:
    To be assured of receiving a passing grade a student must obtain at least 50% of the total weighted marks available for the course (i.e. the Primary Hurdle), and have satisfied the Secondary Hurdle (Supervised), i.e. the end of semester examination by achieving at least 40% of the weighted marks available for that assessment item.

    Supplementary assessment may be offered where a student has undertaken all of the required summative assessment items and has passed the Primary Hurdle but failed to satisfy the Secondary Hurdle (Supervised), or has satisfied the Secondary Hurdle (Supervised) but failed to achieve a passing Final Grade by 5% or less of the total weighted Marks.

    To be awarded a passing grade for a supplementary assessment item (if applicable), a student must achieve at least 50% of the available marks for the supplementary assessment item as per the Assessment Procedure http://policy.usq.edu.au/documents/14749PL (point 4.4.2).

  5. Method used to combine assessment results to attain final grade:
    The final grades for students will be assigned on the basis of the weighted aggregate of the marks obtained for each of the summative assessment items in the course.

  6. Examination information:
    In a Restricted Examination, candidates are allowed access to specific materials during the examination. The only materials that candidates may use in the restricted examination for this course are: writing materials (non-electronic and free from material which could give the student an unfair advantage in the examination); calculators which cannot hold textual information (students must indicate on their examination paper the make and model of any calculator(s) they use during the examination; Students whose first language is not English, may, take an appropriate unmarked non-electronic translation dictionary (but not technical dictionary) into the examination. Dictionaries with any handwritten notes will not be permitted. Translation dictionaries will be subject to perusal and may be removed from the candidate's possession until appropriate disciplinary action is completed if found to contain material that could give the candidate an unfair advantage.

  7. Examination period when Deferred/Supplementary examinations will be held:
    Any Deferred or Supplementary examinations for this course will be held during the next examination period.

  8. University Student Policies:
    Students should read the USQ policies: Definitions, Assessment and Student Academic Misconduct to avoid actions which might contravene University policies and practices. These policies can be found at http://policy.usq.edu.au.

Assessment notes

  1. Attendance at the residential school is Highly Recommended for external and on-campus students (non-attendance will mean the student misses both an element for assessment preparation and an element of assessment).

Other requirements

  1. In order to attend laboratory classes, students must provide and wear appropriate personal protective equipment. This shall include a laboratory coat, closed in shoes, and safety glasses. Such equipment must be approved by supervising staff. Failure to provide and wear the appropriate safety equipment will result in students being excluded from classes.
