Are blue green algae and cyanobacteria the same thing?
What is the difference between cyanobacteria and blue green algae? The cyanobacteria are also called the blue-green algae. Some of the cyanobacteria can be heterotrophs as well. The main difference between green algae and cyanobacteria is that green algae contain chloroplasts whereas cyanobacteria do not contain chloroplasts in their cells.
Why are blue green algae called cyanobacteria?
This event is known as endosymbiosis, and is also the origin of the eukaryotic mitochondrion. Because they are photosynthetic and aquatic, cyanobacteria are often called "blue-green algae".
Is blue green algae a bacterium or algae?

Blue-green algae prefer warm, calm, sunny weather and water temperatures higher than 75 °F. Blooms usually occur during summer and early fall, but can occur other times of the year, if conditions are right.
How do you remove blue-green algae from drinking water?
The best way to get rid of algae in drinking water is with a water filter. The type of water filter required will depend on the type of algae. For example, if there's a chance of blue-green algae (cyanobacteria) – which is actually a bacteria, not algae – nanofiltration, ultrafiltration, or reverse osmosis is best.

What is the difference between green algae and blue-green algae?
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.
What does algae do to water?
As a by-product of photosynthesis, algae also release oxygen into the water that can be used by fish and other aquatic animals. However, when large populations of algae are produced and then die, the process of decomposition also uses oxygen, which can limit its availability for other life in the lake.

That's because the water is still a bit too cold for blue-green algae to flourish. The health department says the algae likes water temperatures in the mid-upper 70s and higher, whereas the lake water is still 71 degrees. That's why the health department says we usually see blooms later in the later summer, like August and early September.

Who is at risk?
Blohm: This type of toxin is not easily absorbed through the skin, so it’s most dangerous when ingested. While adults are not going to drink the water they’re swimming in, kids often do accidentally while diving and playing and dunking their heads. At least with kids, though, you can tell them not to drink the water. At really high risk are dogs.
Why dogs are especially vulnerable?
Blohm: When a dog swims through a bloom, all the cyanobacteria gets stuck in its fur. Once a dog that’s soaked in cyanobacteria gets out of the water and dries off, the bacteria start to die, and that’s when all the toxin gets released. Before the dog licks it up, make sure you wash and dry him or her off.
