Step-by-step solution

Chrysophytes include diatoms and golden algae (desmids). In diatoms, the cell walls are embedded with silica and thus the walls are indestructible. Dinoflagellates are mostly marine and photosynthetic. Most of them have stiff cellulose plates on the outer surface of their cell wall. Euglenoids are mostly 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. Ciliated protozoans are aquatic, actively moving organisms beca
