Plant Physiology Lab

TPSS 470L

Faculty:

Robert Paull

Semesters taught:

Spring 2014, Spring 2015, Spring 2016

Goals:

This laboratory course is designed to expose students to the practical skills required in plant physiology. Techniques and instruments used to study plant metabolic processes, including water relations, respiration, photosynthesis, enzyme kinetics, microscopy, immunochemistry, and nitrogen fixation will be used. Quantitative methods, problem solving, and practical applications are emphasized. These goals will be achieved though both individual and group activities.

The goals of this course aim to assist students to:

  1. Understand basic principles and concepts of plant physiology;
  2. enable students to develop a research framework ;
  3. develop skills in the application of the scientific method;
  4. engage in exercises that require active participation; and
  5. be able to communicate their results and work as a group to solve problems.

Skills and knowledge to be acquired:

Understanding that plant physiology is an experimental science. Provide students with knowledge of the techniques and instruments used to study plant physiology, and develop an understanding of how research in plant physiology is carried out. Quantitative methods, problem solving, and practical applications are emphasized.

Course organization:

The laboratory exercises covered normally in the laboratory are as follows:

  • Lab 1 - Plant growth analysis; Introduction to “Fast Plants”
  • Lab 2 - Water status of plants (osmolarity, stomata, transpiration); Introduce research projects
  • Lab 3 - Water status (pressure bomb);
  • Lab 4 - Respiration (CO2 determination)
  • Lab 5 - Photosynthesis (Chlorophyll, Oxygen, CO2)
  • Lab 6 - Mineral nutrition (extraction, preparation, analysis)
  • Lab 7 - Enzymes (GA and starch breakdown, spectrophotometer)
  • Lab 8 - Cell walls (extraction and analysis, growth)
  • Lab 9 - Research projects proposal presentation
  • Lab 10 - Research projects
  • Lab 11 - Research projects
  • Lab 12 - Research projects
  • Lab 13 - Research projects; Data analysis
  • Lab 14 - Research projects; Data analysis
  • Lab 15 - Research symposium presentation
  • Lab 16 - Research reports due; Lab clean up

Grading:

This laboratory course will include worksheets for most laboratory exercises, as well as one 5-page paper. Attendance and a laboratory notebook will be a significant component of the grade, as will the independent research project.
