Fungi in the environment is a theme which occupies the last section of the course, which reviews the adaptability of the fungi, especially their role in the production and decomposition cycles in terrestrial ecosystems and their abilities to act as mutualistic partners with animals and plants. The next section of the course aims to explore the diversity of form and function in the photosynthetic micro-organisms, particularly where their photosynthetic nature distinguishes them from other groups. A review of the economic importance of photosynthetic micro-organisms, including mass culture, food products and production of toxins follows. The photosynthetic prokaryotes are then discussed, beginning with an account of the photosynthetic systems in oxygenic and anoxygenic bacteria. Cell ultrastructure, morphology, growth and reproduction, nitrogen fixation and heterocyst function in cyanobacteria are then considered.
Practical classes illustrate aspects of the lecture course.
Light microscopy is used to examine a range of micro-organisms. Video microscopy is extensively used to help in interpretation of the practical material. Practicals are assessed by means of tests within the practical classes. Introduction to modern mycology . The biology of fungi .
