Category:Blue-green algae

This category concerns the topic: terms for types or instances of photosynthetic bacteria, also known as cyanobacteria, which were formerly classified as algae.

This category contains no dictionary entries, only other categories. The subcategories are of two sorts:

• Subcategories named like "aa:Blue-green algae" (with a prefixed language code) are categories of terms in specific languages. You may be interested especially in Category:en:Blue-green algae, for English terms.
• Subcategories of this one named without the prefixed language code are further categories just like this one, but devoted to finer topics.

NOTE: This is a set category. It should contain terms for blue-green algae, not merely terms related to blue-green algae. It may contain more general terms (e.g. types of blue-green algae) or more specific terms (e.g. names of specific blue-green algae), although there may be related categories specifically for these types of terms.
