Characteristic of Euglenoids:
fresh water organisms found in stagnant water.
Instead of a cell wall, they have a protein rich layer called pellicle which makes their body flexible.
They have two flagella, a short and a long one.
They are photosynthetic in the presence of sunlight, but behave like heterotrophs by predating on other small organisms in absence of sunlight
pigments are identical to those present in higher plants
Example: Euglena
