a red pigment found in red algae and in few cyanobacteria

aethalium

a spore bearing structure of plasmoidal slime mold

Eugleniod movement

a worm like movement of euglena, accomplished by expanding and contracting the entire cell.

The function of the flagellum that remains in the sulcus is to

act as a rudder
