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 ...
Life forms: (1) Phanerophyte, (2; 3) Chamaephyte, (4) Hemicryptophyte, (5; 6) Geophyte, (7) Helophyte, (8; 9) Hydrophyte. Therophyte and epiphyte are not shown. The Raunkiær system is a system for categorizing plants using life-form categories, devised by Danish botanist Christen C. Raunkiær and later extended by various authors.
The Archaeplastida (or kingdom Plantae sensu lato "in a broad sense"; pronounced / ɑːr k ɪ ˈ p l æ s t ɪ d ə /) are a major group of eukaryotes, comprising the photoautotrophic red algae (Rhodophyta), green algae, land plants, and the minor group glaucophytes. [6]
The distinctions between the genera are artificial, since they do not correspond with monophyletic groupings; [7] occasionally, Ankistrodesmus is found as single cells. [6] Other similar genera include Keratococcus and Elakatothrix. [3] Identification of species chiefly depends on details of the size and shape of cells. [2]
Chlorophytum comosum, usually called spider plant or common spider plant due to its spider-like look, also known as spider ivy, airplane plant, [2] ribbon plant (a name it shares with Dracaena sanderiana), [3] and hen and chickens, [4] is a species of evergreen perennial flowering plant of the family Asparagaceae.
The only known freshwater bivalve with a symbiotic relationship are in the genus Anodonta which hosts the chlorophyte Chlorella in the gills and mantle of the host. [41] In bivalves, photosymbiosis is thought to have evolved twice, in the genus Anodonta and in the family Cardiidae. [ 42 ]
The "DF to Minecraft" utility allows players to view their Dwarf Fortress maps by converting them into Minecraft structures. [70] Adams has acknowledged the role of the community in supporting development and endorsed third-party tools, visualizers and interface code; indeed, he has said that he admires third-party developers who create tools ...
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.
