| The term __"algae"__ is used throughout this wiki in its broadest practical / technical sense, consistent with the definition adopted in European standard EN 17399:2020 and used by CEN/TC 454 and consistent with white paper [[https://www.what-are-algae.com/|What are algae]] by [[https://www.eaba-association.org/en|EABA]].
