Euglenas possess the representative features typical of eukaryotic cells, such as a nucleus, mitochondria, golgi bodies, lysosomes, and vacuoles. The oxidized form of the cytochrome c heme group can accept an electron from the heme group of the cytochrome c1 subunit of cytochrome reductase. Euglena belongs to a group of organisms known as the kinetoplastids, and is of further interest to study because - unlike many of the members of this group, including the trypanosome that causes African sleeping sickness - it does not cause disease. Euglena is a great example of secondary endosymbiosis - the phenomenon which gave eukaryotes their tiny cellular factories, including the chloroplasts which allow plants to photosynthesise. Euglena is a large genus of unicellular protists: they have both plant and animal characteristics. [1], Die sechs bis zwölf abgeflachten, schildförmigen Chloroplasten sind groß und weisen zu beiden Seiten des mittigen Pyrenoids uhrglasförmige Paramylon-Hauben auf. Euglena are usually found to live in fresh water, streams, and in some fresh water ponds. #Euglena #audioversity ~~~ Euglena ~~~ Title: What is Euglena?
