Cyanobacteria vs. Green Algae: What's the Difference?

Edited by Sawaira Riaz || By Sumera Saeed || Updated on October 27, 2023
Cyanobacteria are prokaryotic, photosynthetic bacteria; green algae are eukaryotic, photosynthetic organisms.

Key Differences

Cyanobacteria, often known as blue-green algae, are prokaryotic organisms, meaning they lack a nucleus. Green algae, in contrast, are eukaryotic and possess a defined nucleus.
