Micrasterias is a unicellular green alga of the order Desmidiales. Its species vary in size reaching up to hundreds of microns. Micrasterias displays a bilateral symmetry, with two mirror image semi-cells joined by a narrow isthmus containing the nucleus of the organism.

As a member of the Streptophyta, Micrasterias is not only genetically closely related to higher land plants but shares common features with them in many physiological and cell biological aspects.

Micrasterias may be in the plankton or periphytion of periphyton of acidic, oligotrophic or dystrophic lakes and ponds, or in swamps or mires. There is no clear distinction between Micrasterias and Euastrum, so the placement of certain taxa may be arbitrary.

Oct 4, 2024 · Micrasterias is a fascinating genus of freshwater green algae, belonging to the family of Desmidiaceae. These microscopic heroes are primarily known for their unique shapes and vibrant green coloration.

We scanned the old and developing semicells of dividing Micrasterias, and based on thousands of acquired Raman spectra, we imaged the distribution of organelles and cell constituents such as minerals, lipids, proteins, starch grains, and the primary and secondary cell walls.

Micrasterias is a unicellular green alga of the order Desmidiales. Its species vary in size reaching up to hundreds of microns. Quick Facts Scientific classification, Type species ... See text. Micrasterias displays a bilateral symmetry, with two mirror image semi-cells joined by a narrow isthmus containing the nucleus of the organism.

Micrasterias is most studied among desmids for chromosome numbers and karyotype analysis. Chromosome numbers from 24-230 among 18 species; strains of single species may have different numbers. Morphological variants in culture are aneuploids (Guiry and Guiry 2013). Similar genera: Habitat: Acidic, oligotrophic freshwater bogs and lakes.

Micrasterias furcata is a species of unicellular desmid which inhabits freshwater areas. M. furcata is round, flattened and lobed in body plan. [1]

Micrasterias is a unicellular placoderm desmid with large, solitary, flattened semicells that are usually elaborately lobed. In some species, the semicells are simpler and look like flattened disks. Others have intricately lobed semicells with incisions that create a starlike pattern of projections.
