In the cells of most plants, crystals consisting of calcium oxalate are found which are formed by a process called  biomineralisation. It is thought that these crystals act as a storage reservoir for calcium and also provide for the storage of toxic waste (detoxification). The crystals come in a variety of shapes and some are characteristic of certain plant groups.

Unprepared leaves can provide a surprising view through a microscope.
