* Mixotrophic: This means they can obtain energy through both photosynthesis (like plants) and by consuming other organisms (like animals). They contain chloroplasts for photosynthesis and can also engulf food particles.
* Flagella: Euglena have one or two whip-like structures called flagella that help them move through water.
* Eyespot: This is a light-sensitive organelle that helps the euglena find the best light conditions for photosynthesis.
* Pellicle: A flexible, protein-rich layer beneath the cell membrane that helps maintain their shape.
