Study and evaluate your knowledge of the structure of a Euglena with the following set of free euglena diagram. This diagram provides a simplified overview of the anatomy of a Euglena so you can use these diagrams to aid your study. Below is the first simple diagram which shows the parts of the Euglena.
Euglena is a genus of single cell flagellate eukaryotic. Species of Euglena are found in freshwater and salt water. They are often abundant in quiet inland waters where they may bloom in numbers sufficient to color the surface of ponds and ditches green or red. This protist is both an autotroph, meaning it can carry out photosynthesis and make its own food like plants, as well as a heterotroph, meaning it can also capture and ingest its food. The following euglena diagrams show the structures of the euglena.
Locomotion comes in the form of either the rotating flagellums or the flexible pellicle membrane. The euglena has a stiff pellicle outside the cell membrane that helps it keep its shape, though the pellicle is somewhat flexible and some euglena can be observed scrunching up and moving in an inchworm-type fashion. In the center of the cell is the nucleus, which contains the cell’s DNA and controls the cell’s activities. The nucleolus can be seen within the nucleus.
The interior of the cell contains a jelly-like fluid substance called cytoplasm. Toward the posterior of the cell is the contractile vacuole. These diagrams show you an in-depth and satisfying understanding of the euglena structures. Click on any of these diagrams for a better view!
