Secondary Description
Author: Wehr, J. D. and Sheath, R. G., (eds.), 2003
Secondary Description:
Cells are pink or red in color because of the presence of phycoerythrin, and they are comma-shaped, with an acute tail that lacks true plates. There is a ventral furrow (=sulcus, a deep furrow rather than a gullet). The periplast consists of an internal component (IPC) of hexagonal plates, whereas rosette scales make up the surface periplast component (SPC). The acute tail has a continuous periplast sheet rather than plates. Thylakoids usually occur in groups of three.
