Chrysophytes are a group of photosynthetic protists commonly found in freshwater and marine environments. According to the standard biological classification (such as NCERT/Whittaker), this group specifically includes:

Diatoms: Characterized by silica-embedded cell walls that form two overlapping shells fitting together like a soapbox.

Desmids: Also known as golden algae, these are typically found in freshwater and are noted for their distinctive golden-brown coloration.
