Content
Plants have literally shaped the Earth and its environment, priming the great oxygenation event several billion years ago which enabled the evolution of all aerobic life. We are sustained by the bountiful plant life around us, but it is their capacity to adapt and acclimate to wide conditions that makes studying plants so interesting. This plasticity driven by the plant genome underpins native ecosystems, enables restoration of toxic or nutrient-poor land, as well as use of plants in managed systems including agriculture. Plants also have a wide range of relationships with other organisms, from food or host to symbiont or parasite. Grain/seed production sustains the energy requirements of the growing human population, as well as being one of the major international commodities traded around the world. Plant metabolic pathways facilitate acclimation to a changing environment and produce compounds (e.g. vitamins) essential for human and animal health. This unit takes students through the parts (organs, tissues and cells) that make up plants, and considers the relationships and influences of plants on the environment and other organisms. Students will gain practical skills in evaluating plant function in the context of many disciplines. Topics include the structure–physiology relationships at the cell, tissue, organ, plant and community levels; plant growth and development; transfer processes in the soil–plant–atmosphere continuum; energy capture and metabolism; water relations; nutrient acquisition; and acclimations to environment.
Outcomes
Students are able to (1) know the structure of plants and how each part functions and contributes to the whole; (2) have skills in plant anatomy and measure aspects of plant physiology including net photosynthesis, chlorophyll content, water relations, water transport, ion transport, radiation interception, and plant growth and development; and (3) have skills in quantitative analyses, critical thinking to evaluate data sets and communicate findings, and several foundation theories in plant physiology.
Assessment
Indicative assessments in this unit are as follows: (1) continuous assessment corresponding to the practical sessions (45 per cent) and (2) end-of-semester two-hour examination (55 per cent). Further information is available in the unit outline.

Supplementary assessment is not available in this unit except in the case of a bachelor's pass degree student who has obtained a mark of 45 to 49 overall and is currently enrolled in this unit, and it is the only remaining unit that the student must pass in order to complete their course.

  • The availability of units in Semester 1, 2, etc. was correct at the time of publication but may be subject to change.
  • All students are responsible for identifying when they need assistance to improve their academic learning, research, English language and numeracy skills; seeking out the services and resources available to help them; and applying what they learn. Students are encouraged to register for free online support through GETSmart; to help themselves to the extensive range of resources on UWA's STUDYSmarter website; and to participate in WRITESmart and (ma+hs)Smart drop-ins and workshops.
  • Books and other material wherever listed may be subject to change. Book lists relating to 'Preliminary reading', 'Recommended reading' and 'Textbooks' are, in most cases, available at the University Co-operative Bookshop (from early January) and appropriate administrative offices for students to consult. Where texts are listed in the unit description above, an asterisk (*) indicates that the book is available in paperback.
