16: PHOTOSYNTHESIS in silico
Photosynthesis, the biological process by which light energy is used to convert carbon dioxide and water to sugars, is fundamental to life on Earth and as such a vital component of most undergraduate biology courses. Like respiration it is a complex process and, despite its central importance, remains an area which students find difficult to comprehend. This difficulty is compounded by the expense and complexity of the equipment available for practical teaching in photosynthesis, making it virtually impossible to provide hands-on learning to the large class sizes in most undergraduate biology degrees.
An interactive multimedia software package has been produced comprising 5 modules. These include:
- animations of the photosynthetic electron transport chain and ATP synthase.
- simulated experimental models of gas exchange and fluorescence which can be used either as stand-alone packages or, where equipment is available, to supplement and enrich a laboratory demonstration/ experiment. These include 2 introductory level practicals on the effects of light quality and quantity on photosynthesis in the aquatic plant Egeria, and an advanced level module describing the use of chlorophyll fluorescence techniques to measure photosynthesis.
- theory modules which describe the responses of plants to sun and shade and excess light environments.
Our philosophy in producing these modules was to enhance the classroom and particularly the practical experience of students within the University. These modules are currently used by students at all levels, ranging from 1st year undergraduate to PhD students. Feedback from students has been excellent and their understanding of the concepts involved has increased dramatically.
