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 ...
An example of Chlorophyceae genus Pediastrum.. The Chlorophyceae are a class of green algae, distinguished mainly on the basis of ultrastructural morphology.They are usually green due to the dominance of pigments chlorophyll a and chlorophyll b.
Depending on the species, Chlorophyceae can grow unicellular (e.g. Chlamydomonas), colonial (e.g. Volvox), filamentous (e.g. Ulothrix), or multicellular. [example needed] They are usually green due to the presence of chlorophyll a and chlorophyll b; they can also contain the pigment beta-carotene.
Members of this class are coccoid green cells, with a diameter of 1.5–4 μm, found in marine waters, with one nucleus, one mitochondrion, and one chloroplast surrounded by two membranes, containing starch grain; their single chloroplast has chlorophylls a and b; they lack pyrenoid and flagella; and they have a layered cell wall.
The Viridiplantae diverged into two clades. The Chlorophyta include the early diverging prasinophyte lineages and the core Chlorophyta, which contain the majority of described species of green algae. The Streptophyta include charophytes and land plants. Below is a consensus reconstruction of green algal relationships, mainly based on molecular ...
This category contains valid Chlorophyta species names. Alternate names (i.e. junior synonyms) are not included here. Italicized entries are articles about species in monotypic genera; these are redirected to their appropriate genus article.
Scenedesmus is one of the most common freshwater algae genera; however, the extremely diverse morphologies found within species make identification difficult. [4] While most species are found across the world, certain species exist only in local populations such as S. intermedius and S. serratus which are found in New Zealand.
