Euglenoids

- Habitat:Â Primarily freshwater organisms inhabiting stagnant water.
- Cell Structure:Â Lack a rigid cell wall; possess a protein-rich layer called a pellicle, providing flexibility.
- Movement:Â Equipped with two flagella, one short and one long, for locomotion.
- Nutrition:Â Exhibit mixotrophic nutrition:
- Photosynthetic in the presence of sunlight (autotrophic).
- Heterotrophic in the absence of sunlight, predating on smaller organisms.
- Pigments:Â Contain photosynthetic pigments identical to those found in higher plants (chlorophyll a and b).
- Example:Â Euglena
