Cyanobacteria are a very large and diverse phylum of photosynthetic prokaryotes. They are defined by their unique combination of pigments and their ability to perform oxygenic photosynthesis. They often live in colonial aggregates that can take on a multitude of forms.
Sep 16, 2022 · Cyanobacteria Definition. Cyanobacteria is a group of photosynthetic bacteria widely distributed in various aquatic habitats (oceans, seas, rivers, lakes, etc.) and terrestrial habitats (e.g. moist soils). They may live singly or in colonies (by forming filaments or spheres with other cyanobacteria).
Jul 14, 2024 · Blue-green algae, any of a large, heterogeneous group of prokaryotic, principally photosynthetic organisms. Cyanobacteria resemble the eukaryotic algae in many ways, including morphological characteristics and ecological niches, and were at one time treated as algae, hence the common name of.
May 25, 2015 · Cyanobacteria are single-celled organisms with prokaryotic cells but will often form colonies with individual cells working together, often arranged into long stringy filaments. Certain cyanobacteria cells, known as heterocytes, have the ability to fix nitrogen and work in unison with other cells.
: any of a major group (Cyanobacteria) of photosynthetic bacteria that are single-celled but often form colonies in the form of filaments, sheets, or spheres and are found in diverse environments (such as salt and fresh water, soils, and on rocks)
Dec 24, 2022 · cyanobacteria: Cyanobacteria, also known as blue-green bacteria, blue-green algae, and Cyanophyta, is a phylum of bacteria that obtain their energy through photosynthesis. photosynthesis: The process by which plants and other photoautotrophs generate carbohydrates and oxygen from carbon dioxide, water, and light energy in chloroplasts.
Cyanobacteria are aquatic and photosynthetic, that is, they live in the water, and can manufacture their own food. Because they are bacteria, they are quite small and usually unicellular, though they often grow in colonies large enough to see. They have the distinction of being the oldest known fossils, more than 3.5 billion years old, in fact!
