DNA barcoding of algae is commonly used for species identification and phylogenetic studies. Algae form a phylogenetically heterogeneous group, meaning that the application of a single universal barcode/ marker for species delimitation is unfeasible, thus different markers/barcodes are applied for this aim in different algal groups.
Marine algae can be divided into six groups: green, red and brown algae, euglenophytes, dinoflagellates and diatoms. Dinoflagellates and diatoms are important components of marine algae and have their own sections below. Euglenophytes are a phylum of unicellular flagellates with only a few marine members. Not all algae are microscopic.
The chloroplasts of red algae have chlorophylls a and c (often), and phycobilins, while those of green algae have chloroplasts with chlorophyll a and b without phycobilins. Land plants are pigmented similarly to green algae and probably developed from them, thus the Chlorophyta is a sister taxon to the plants; sometimes the Chlorophyta, the ...

A nitroplast is an organelle found in certain species of algae, particularly in the marine algae Braarudosphaera bigelowii. [1] It plays a crucial role in nitrogen fixation , a process previously thought to be exclusive to bacteria and archaea .
Green water is an algae infestation that is suspended in aquarium water. It does not settle on surfaces. They are typically of the genera Chlorella, Ankistrodesmus, and Scenedesmus. It is a very common infestation to have in newly established aquaria, but may also occur after temperature swings or nutrient imbalances. [7] Once established ...
Chlamydomonas species are widely distributed worldwide in soil and fresh water, of which Chlamydomonas reinhardtii is one of the most common and widespread. [1] C. reinhardtii is an especially well studied biological model organism , partly due to its ease of culturing and the ability to manipulate its genetics.
Chlamydomonas (/ ˌ k l æ m ɪ ˈ d ɒ m ə n ə s,-d ə ˈ m oʊ-/ KLAM-ih-DOM-ə-nəs, -də-MOH-) is a genus of green algae consisting of about 150 species [2] of unicellular flagellates, found in stagnant water and on damp soil, in freshwater, seawater, and even in snow as "snow algae". [3]
