Solution:

Euglenoids are unicellular freshwater organisms with two flagella (one long one short) belonging to the kingdom Protista and are found in stagnant water. These organisms instead of a cell wall possess a protein-rich layer called pellicle, which helps to make their body flexible. They can act as autotrophs in presence of sunlight as well as heterotrophs in absence of it.
