Scales in riccia

2. The pigment anthocyanin is what gives violet its colour.
3. In Riccia, the scales are ligulate.
4. By protecting the growing point's delicate cells and secreting slime to keep them moist, the scales help to protect it.
5. Riccia fluitans is one aquatic member of the Marchantiales group that lacks scales.
6. In riccia, the purpose of the scales is a defence against grazing animals.
7. Scales frequently cover the ventral surface of the thallus.
