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>
        
                    
             
        
        
        
1)Enzyme is a protein. The main material of an enzyme is protein 
2)It is easily influenced, by environmental change. Environmental factors include temperature, pH, and inhibitor. 
3)It acts as catalyst The enzyme functions in accelerating chemical reaction, but the enzyme itself does not change after the reaction ends.
