Chlorophyte algae use a dehydrogenase inside the mitochondria to process glycolate during photorespiration. In contrast, streptophytes (including land plants) use peroxisomes that contain glycolate oxidase , which converts glycolate to glycoxylate , and the hydrogen peroxide created as a subproduct is reduced by catalases located in the same ...
Volvox carteri [1] is a species of colonial green algae in the order Volvocales. [2] The V. carteri life cycle includes a sexual phase and an asexual phase.V. carteri forms small spherical colonies, or coenobia, of 2000–6000 Chlamydomonas-type somatic cells and 12–16 large, potentially immortal reproductive cells called gonidia.

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.
Traditionally, families and genera within Chlamydomonadales have been classified based on their morphology. However, molecular phylogenetic studies have shown that the evolutionary relationships do not correspond to the traditional taxonomic classifications. Despite this, the families and genera are still in use, because the differences have ...
Green algae are a group of photosynthetic, eukaryotic organisms that include species with haplobiontic and diplobiontic life cycles. The diplobiontic species, such as Ulva , follow a reproductive cycle called alternation of generations in which two multicellular forms, haploid and diploid, alternate, and these may or may not be isomorphic ...
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]
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.
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]
