In this introductory course on Plant biology, the focus is on understanding the development, structure and functioning of plants. Emphasis is placed on the relations between cellular and molecular processes at one side and the functioning of the whole plant in its environment at the other side. The course consists of a cell biological/structural part (with emphasis on cell structure and organisation, cell division, genetic regulation, plant morphogenesis, differentiation and interaction between plants and micro-organisms) and a physiological part (focussing on e.g. photosynthesis, respiration, water and ion transport, regulation of growth by plant hormones and light).
