are algae single celled
They are neither plant, animal or fungi. Many algae are single celled, however some species are multicellular. Many, but not all of red and brown algae are multicellular. Red and brown algae are common in marine environments. Some green algae are multicellular. Green algae may be unicellular (one cell), multicellular (many cells), colonial (living as a loose aggregation of cells) or coenocytic (composed of one large cell without cross-walls; the cell may be uninucleate or multinucleate). They have membrane-bound chloroplasts and nuclei. The main phylogenetic groups of algae are [1] , [2] : : 1  unicellular organisms of the kingdom protista, characterized by a silica shell of often intricate and beautiful sculpturing. 1 : small phylum of the kingdom protista, consisting of mostly unicellular aguatic algae. 2  Some euglenoids contain chloroplasts with the photosynthetic pigments; others are heterotrophic and can ingest or absorb their food. 3  Reproduction occurs by longitudinal cell division. 4  Most live in freshwater. Blue-green algae are not actually algae, they are bacteria. Green algae cells have nuclei and the pigment is distinct. Green algae are the most common algae in ponds and can be multicellular. Euglenoids are green or brown and swim with their flagellum, too. They are easy to spot because of their red eye. Euglenoids are microscopic and single celled. 1 : phylum of prokaryotic aguatic bacteria that obtain their energy through photosynthesis. 2  They are often referred to as blue-green algae, even though it is now known that they are not related to any of the other algal groups, which are all eukaryotes. 3  Cyanobacteria may be single-celled or colonial. 1 Basic Understanding of Micro and Macro Algae If you have been doing your homework with regard to setting up a saltwater aquarium you should have come across the terms micro and macro with regard to algae. 2  However, if yo…. 3  The Five Major Parts of the Brain At its most basic, the brain controls the body. Life was indeed very simple when all green-coloured algae were included in a single class, the Chlrophyceae. Increasingly, it has become clear that the green algae are very diverse in their relationships and are now included in two phyla (Chlrophyta and Charophyta) and at least 17 classes!
