Euglenoid - definition of euglenoid by The Free Dictionary

Euglenoids are distinguished mainly by the presence of a type of cell covering called a pellicle. Within its taxon, the pellicle is one of the euglenoids' most diverse morphological features. The pellicle is composed of proteinaceous strips underneath the cell membrane, supported by dorsal and ventral microtubules. This varies from rigid to flexible, and gives the cell its shape, often giving it distinctive striations. In many euglenids, the strips can slide past one another, causing an inchi… WebApr 7, 2024 · Euglena comes under the category of eukaryotes, meaning it has a nucleus within its cell membrane.
