Euglenophyta is a group of single-celled organisms known as euglenoids, primarily found in freshwater environments. They are unique because they possess both plant-like and animal-like characteristics. Euglenoids contain chloroplasts, allowing them to perform photosynthesis, but they can also consume organic matter when light is unavailable. These organisms typically have a flexible outer covering called a pellicle, which helps them maintain their shape. Euglenophyta can move using a whip-like structure called a flagellum, enabling them to swim toward light or nutrients. This adaptability makes them important in aquatic ecosystems.
