Abstract
With a few exotic exceptions, life on earth depends on the energy captured by photosynthesis in green plants and algae. Now, as every holidaymaker will be aware, the sun does not shine on demand, particularly in the British Isles, and this applies not only to melanin-starved holidaymakers but also to plants. Plants therefore need some mechanism by which energy can be stored in chemical form. This is particularly important where the plant is exposed to an inhospitable climate, such as winter or drought, for prolonged periods and where relatively large amounts of energy need to be stored to guarantee survival of the species. In these conditions energy storage in the form of simple mono- or disaccharides has certain limitations. High concentrations of sugar can lead to high osmotic pressures within the cell and high viscosities, both of which the cell may be unable to tolerate.
