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 ...
Volvox is a polyphyletic genus of chlorophyte green algae in the family Volvocaceae. Volvox species form spherical colonies of up to 50,000 cells, and for this reason they are sometimes called globe algae. They live in a variety of freshwater habitats, and were first reported by Antonie van Leeuwenhoek in 1700.
Cladophora possesses unprecedented capacities to filter toxins from water such as heavy metals and pollutants and efficiently absorb nutrients, including nitrogen and phosphorus. [ 3 ] Cladophora is known for its blooming activities which are seasonal, (early spring to summer) and indicate their eutrophic abilities as well as that pollution may ...
The green algae, including the characean algae, have served as model experimental organisms to understand the mechanisms of the ionic and water permeability of membranes, osmoregulation, turgor regulation, salt tolerance, cytoplasmic streaming, and the generation of action potentials.
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 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]
Sponges (phylum Porifera) have a large diversity of photosymbiote associations. Photosymbiosis is found in four classes of Porifera (Demospongiae, Hexactinellida, Homoscleromorpha, and Calcarea), and known photosynthetic partners are cyanobacteria, chloroflexi, dinoflagellates, and red and green (Chlorophyta) algae.
Mougeotia is able to reproduce sexually, through a process known as conjugation. It is isogamous, with two different but identically appearing gamete types. [4]In scalariform conjugation, cells of two separate filaments line up parallel to one other.
