Galls are the proliferation of cell tissue in plants and can be caused by various living agents from fungi and bacteria, to various insects and mites. Often, they are very organised structures and because of this, the cause of the gall can often be determined without the actual agent being identified. This applies particularly to some insect and mite galls.
