Provided here is a collection of Euglena Diagrams labeled to help you learn the structures and parts of a Euglena for your test, quiz, or biology class. Euglena is single-celled organisms that belong to the genus protest, and neither plants, animal or fungi. Browse the diagrams in the following images.

You can see in the Euglena Diagram above that in particular, Euglena share some characteristics of both plants and animals. While they can manufacture their own food, a characteristic seen in plants, they are also capable of movement and also consume food, which are characteristics of animals. Most species of Euglena have photosynthesizing chloroplasts within the body of the cell, which enables them to feed by autotrophy, like plants. More Euglena diagrams are posted below.


Euglena’s body is surrounded by a tough & elastic membrane called the pellicle. In the middle of the anterior end lies a cytostome leading into a small cytopharynx which dialates behind into a reservoir. Near the reservoir a large contractile vacuole is present. Ectoplasm full of myonemes and endoplasm has a small rounded nucleus and conspicuous chloroplasts arranged like a star.


Euglena does their reproduction through longitudinal binary fission, but in adverse circumstances through encystment and palmella stage. They are also eukaryotic unicellular organism with major organelles found in a more complex life. Euglena utilizes its chloroplasts (which gives it the green color) to produce sugars by photosynthesis. Studying through these diagrams is a great and easy way to assess understanding of Euglena structure. Download and print the diagrams today!
