Definition

Noun (plural, treated as singular) 1.

Usage Notes

• The term "Myxophyceae" is archaic and no longer used in modern scientific taxonomy. It is primarily encountered in historical biological literature.

Examples

Advanced Usage

• The shift from "Myxophyceae" (implying a relationship with algae) to "Cyanobacteria" reflects the advancement in biological understanding, specifically the distinction between prokaryotic bacteria and eukaryotic algae.

Variants and Related Words
