Chlorophyceae can reproduce both asexually and sexually. In asexual reproduction, cells may produce autospores, aplanospores or zoospores. Autospores (by definition) lack flagella and appear as smaller versions of vegetative cells. Zoospores typically have an elongate, hydrodynamic shape and often have eyespots.
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.
Green algae Green algal diversity. From top left corner: Picocystis (Picocystophyceae), Acetabularia (Ulvophyceae), Botryococcus (Trebouxiophyceae), Volvox (Chlorophyceae), Klebsormidium (Klebsormidiophyceae), Chara (Charophyceae), Spirogyra and Micrasterias (Zygnematophyceae)
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 ...
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.
Chaetophorales is an order of green algae in the class Chlorophyceae. [1] Algae in the order Chaetophorales consist of filamentous, branched algae. The thalli have two parts, a prostrate and upright section and the filaments are variously branched. The algae are found in freshwater habitats or terrestrial habitats. [2]
The prasinophytes are a group of unicellular green algae. [4] Prasinophytes mainly include marine planktonic species, as well as some freshwater representatives. [4] [5] The prasinophytes are morphologically diverse, including flagellates with one to eight flagella and non-motile (coccoid) unicells.
Chlamydomonadales, also known as Volvocales, are an order of flagellated or pseudociliated green algae, specifically of the Chlorophyceae. [1] Chlamydomonadales can form planar or spherical colonies. These vary from Gonium (four to 32 cells) up to Volvox (500 cells or more).
