Question

Under the Kingdom Protista, which organisms, often called 'golden algae', are placed along with diatoms?

• A. Dinoflagellates
• B. Desmids
• C. Slime moulds
• D. Euglena

Hint:

Remember the important Protista groups: \[ \boxed{\text{Chrysophytes} \rightarrow \text{Diatoms + Desmids (Golden algae)}} \] \[ \boxed{\text{Euglenoids} \rightarrow \textit{Euglena}} \] \[ \boxed{\text{Dinoflagellates} \rightarrow \text{Red tides}} \] Golden algae are commonly referred to as desmids in NCERT.

Answer 1

The Correct Option is B

Chrysophytes, commonly called golden algae or diatoms, belong to Kingdom Protista and are photosynthetic, mostly unicellular organisms found in freshwater and marine environments. Their cell walls (frustules) are composed of silica and they are the chief producers of aquatic ecosystems.
