A family of single-celled green algae that includes the chlorella genus, classified scientifically in taxonomy.
From Chlorella + -aceae (the standard Latin suffix for biological families). Follows Linnaean taxonomy naming conventions established in the 18th century.
The '-aceae' suffix is biology's family name marker—once you see it, you know you're looking at a whole family of related organisms, like how all roses belong to Rosaceae.
