Question

Why are dinoflagellates called armoured dinoflagellates?

Answer 1

Dinoflagellates

1. Dinoflagellates are unicellular protists comprising two flagella
2. Dinoflagellates are known as armoured dinoflagellates because they have sculptured plates.
3. A complex covering known as the amphiesma surrounds dinoflagellates and is made up of inner and outer continuous membranes, as well as a number of flattened vesicles.
4. These vesicles house the thecal plates, which are cellulose plates that serve as the "armour" in armoured forms.
