For the purposes of considering applications for Reasonable Adjustments under the Disability Standards for Education (Cwth 2005) and Students Experiencing Academic Disadvantage Policy, this subject requires all students to actively and safely participate in practical class activities. Students who feel their disability may impact upon their participation are encouraged to discuss this with the Subject Coordinator and the Disability Liaison Unit. http://www.services.unimelb.edu.au/disability/

This subject examines the critical roles that plants play in life on earth. It explores how plants capture energy and carbon in the biosphere and influence the atmosphere; absorb almost all mineral nutrients that enter our ecosystem and underpin the nutrition and food supply of animals and people; have a major effect on hydrology and climate due to their water use; and produce a wealth of products ranging from food on our plates to fuel for our cars. Weekly practicals allow hand-on experience with plants and involve experiments with light, gravity, nutrients and additional factors that affect plant growth. Topics covered include:

• Carbon and energy: gas exchange and atmosphere, plant productivity, carbon crediting, climate change, artificial environments;
• Water: uptake and loss, plants and the hydrological cycle, coping with drought, salinity and temperature extremes;
• Nutrition: essential elements, metabolic requirements, plants as part of the global nutrition cycle, biofortification to produce nutrient-enriched food;
• Renewable energy: biohydrogen, biofuels such as bioethanol and biodiesel, future directions for the biofuel industry.

The objectives of this subject are to:

• introduce plant structure and function in relation to the physical environment;
• demonstrate how a fundamental knowledge of plant structure and function is critical to understanding major global processes such as climate change, hydrology and agriculture;
• understand how plants adapt to natural environments and how they can be modified to survive in new environments and/or provide new products;
• increase awareness of environmental issue that affect plants in Australia;
• provide skills in laboratory-based experimental plant science.

Four practical assignments (up to 3000 words in total) evenly spaced through the semester (35%); a 2-hour written examination in the examination period (65%).

This subject potentially can be taken as a breadth subject component for the following courses:

• Bachelor of Arts
• Bachelor of Commerce
• Bachelor of Environments
• Bachelor of Music

You should visit learn more about breadth subjects and read the breadth requirements for your degree, and should discuss your choice with your student adviser, before deciding on your subjects.

At the completion of the subject students should have:

• knowledge of plant structure and function in relation to the physical environment;
• knowledge of how plants can be used to solve environmental problems;
• knowledge of environmental issues that affect plant function in Australia; and
• skills in laboratory-based experimental plant science.

This subject is available for science credit to students enrolled in the BSc (both pre-2008 and new degrees), BASc or a combined BSc course.
