This 12-inch glass plate depicts a microscopic view of the region of water surrounding the algae known as the phycosphere. The phycosphere is like a treasure trove for microorganisms, such as bacteria, that surround the algae, filled with tasty treats. The bacteria position themselves close to the algae or on its surface. The bacteria that reside in the phycosphere and near algae are known as planktonic, whereas bacteria that cling to the algae or lie flat on it are called attached bacteria.
