Euglenoids <span>are unicellular protists commonly found in fresh </span>water.They don not have a cell<span> wall, despite that, a protein rich </span>cell membrane called pellicle is present in Euglenoids.
Whereas,<span>Algae are eukaryotic organisms comprising of no roots, stems, or leaves but they filled with chlorophyll and other pigments to carry out the process of photosynthesis. Similar to </span>Euglenoids, they<span> occur most frequently in water, specifically in plankton.
</span>Hence,
Euglenoids and algae share a common characteristic,that is both are autotrophs. They <span>produce complex organic compounds from simple substances present in their surroundings, by the use of energy from sun-light or inorganic chemical reactions.</span>
