Furthermore, a significant difference between blue green algae and green algae is that the blue green algae do not possess chloroplasts, and other membrane-bound organelles while green algae possess chloroplasts and membrane-bound organelles.If you see leaves or roots, or distinguishable parts, it’s likely a tiny (and harmless) aquatic plant like duckweed. Stringy, silky substances that can be draped over a stick are green algae. If it’s yellow and almost “dusty” in texture, it might act like blue-green algae, but it’s actually tree pollen.Main Difference – Green Algae vs Cyanobacteria
Green algae are eukaryotes but, cyanobacteria are prokaryotes. Therefore, the green algae contain membrane-bound organelles along with a nucleus. In contrast, cyanobacteria do not have membrane-bound organelles. The cyanobacteria are also called the blue-green algae.
