Chlorophytes are eukaryotic organisms composed of cells with a variety of coverings or walls, and usually a single green chloroplast in each cell. [4] They are structurally diverse: most groups of chlorophytes are unicellular, such as the earliest-diverging prasinophytes, but in two major classes (Chlorophyceae and Ulvophyceae) there is an evolutionary trend toward various types of complex ...
Spirogyra (common names include water silk, mermaid's tresses, and blanket weed) is a genus of filamentous charophyte green algae of the order Zygnematales, named for the helical or spiral arrangement of the chloroplasts that is characteristic of the genus.
All Chlamydomonas are motile, unicellular organisms. Cells are generally spherical to cylindrical in shape, but may be elongately spindle-shaped, [9] and a papilla may be present or absent.
Chlorella is a genus of about thirteen species of single-celled or colonial green algae of the division Chlorophyta.The cells are spherical in shape, about 2 to 10 μm in diameter, and are without flagella.
The plant body is a gametophyte. It consists of the main axis (differentiated into nodes and internodes), dimorphic branches (long branch of unlimited growth and short branches of limited growth), rhizoids (multicellular with oblique septa) and stipulodes (needle-shaped structures at the base of secondary laterals).
Both the "chlorophyte algae" and the "streptophyte algae" are treated as paraphyletic (vertical bars beside phylogenetic tree diagram) in this analysis. [ 22 ] [ 23 ] The classification of Bryophyta is supported both by Puttick et al. 2018, [ 24 ] and by phylogenies involving the hornwort genomes that have also since been sequenced.
Chlorella vulgaris has been the microalgae of choice for several bioremediation processes. Owing to its ability to remove a variety of pollutants such as inorganic nutrients (nitrate, nitrite, phosphate and ammonium), fertilizers, detergents, heavy metals, pesticides, pharmaceuticals and other emerging pollutants from wastewater and effluents, carbon dioxide and other gaseous pollutants from ...
The flowers are small and usually white, produced on sparse panicles up to 120 cm (47") long. In certain species, such as C. comosum (the ubiquitous 'spider plant'), the plants are known to reproduce vegetatively by producing plantlets—baby plants connected by an "umbilical" stem, sprouting from the side of the main mother-plant. On the ...
