SAPS Student Project - sweet and sour project 
This is a SAPS student project starter, for Biology students studying A-levels, Scottish Highers and IB who are planning their independent investigation. It contains ideas for investigations on a topic, and outlines of the scientific techniques needed for these investigations.
Fruits evolved as a means of dispersing the offspring of the plant (the seeds) well away from the parent plant. For plants that produce succulent fruit this requires the cooperation of animals which are tempted to eat the fruit. It is the attractive taste that rewards the cooperative animal, as well as the energy rich meal provided by the flesh of the fruit. However, it is essential that the fruit avoids 'premature' consumption. In fact, unripe fruit may even carry distasteful chemicals as a deterrent. In this project starter, you’ll think about how you can investigate the levels of sweetness and sourness in fruit.
