Blue-green algae are also known as what?

Blue-green algae are cyanobacteria, a group of photosynthetic bacteria. They are prokaryotes, not true algae, fungi, protozoa, or viruses. The name comes from their blue-green coloration and ability to photosynthesize, but they belong to the bacterial domain. In water, they can form blooms and sometimes produce toxins that affect drinking and recreational water, making monitoring for cyanobacteria important in public health. Cyanobacteria also contain chlorophyll a and pigments like phycocyanin and phycoerythrin, which contribute to their distinctive color.
