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 ...
Free Fire grossed $1.4 million in the United States and Canada, and $1.2 million in other territories, for a total of $2.6 million. [3] In the United States and Canada, Free Fire opened alongside The Promise, Born in China, Unforgettable and Phoenix Forgotten, and was projected to gross around $3 million from 1,070 cinemas in its opening ...
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.
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.
This list of genera in Chlorophyceae is sub-divided by order and family. Some genera have uncertain taxonomic placement and are listed as incertae sedis . The list is based on the data available in AlgaeBase , the Integrated Taxonomic Information System (ITIS) and other taxonomic databases.
Chlorophytum (/ ˌ k l ɒr ə ˈ f aɪ t əm, ˌ k l ɔː-,-r oʊ-/, [3] [4]), sometimes colloquially referred to as the spider plants, is a genus of almost 200 species of evergreen perennial flowering plants in the century plant subfamily within the asparagus family. [5]
