What is the difference between algae and cyanobacteria?
Best insight from top research papers
Algae and cyanobacteria differ in their cellular structure and genetic diversity. Algae are eukaryotic organisms with a nucleus and other organelles, while cyanobacteria are prokaryotes lacking these structures . Cyanobacteria, also known as blue-green algae, are photosynthetic bacteria that contain pigments like chlorophyll, giving them a green color, and beta-carotene, which contributes to a red hue . In contrast, algae are primarily multicellular organisms with larger cell sizes and diverse forms, including seaweeds and microalgae . Cyanobacteria are particularly efficient in biomass production and can be cultivated in various environments, including wastewater, making them valuable for bio-fertilizer production and biofuel generation . Algae, on the other hand, are derived from living sources like animals and plants, with limitations in land use and biomass production compared to cyanobacteria.
