Other eukaryotic cells
Eukaryotes
are a very diverse group, and their cell structures are equally
diverse. Many have cell walls; many do not. Many have chloroplasts,
derived from primary, secondary, or even tertiary endosymbiosis; and
many do not. Some groups have unique structures, such as the cyanelles
of the glaucophytes, the haptonema of the haptophytes, or the
ejectisomes of the cryptomonads. Other structures, such as pseudopods,
are found in various eukaryote groups in different forms, such as the
lobose amoebozoans or the reticulose foraminiferans.
