The sporophyte produces haploid spores by meiosis that germinate to produce a multicellular gametophyte. It is considered a Paraphyletic Group. Words. Examples: Cephaleuros, Oedocladium Since the realization that the embryophytes emerged from within the green algae, some authors are starting to include them. Green Algae as Ancestors of Land Plants: Because of morphological, cytological and biochemical similarities, and phylogenetic evidences, it is now believed that green algae are the ancestors of land plants. Chlorococcales. Cyanobacteria: Nostoc, Anabaena, Oscillatoria, and Spirulna are examples of cyanobacteria. These Algae consists of photosynthetic pigments eg.� chlorophyll a�and b. The Chlorophyta include the early diverging prasinophyte lineages and the core Chlorophyta, which contain the majority of described species of green algae. In the Green Algae sexual reproduction is communal. [9] Many species live most of their lives as single cells, while other species form coenobia (colonies), long filaments, or highly differentiated macroscopic seaweeds. In this reproduction type gametes are formed which have two or four flagella. This process is called conjugation and occurs for example in Spirogyra. The brown algae are the only ones that are not known to be unicellular, and all three are autotrophs, or self-feeders. Prominent examples of green algae include Spirogyra, Ulothrix, Volvox, etc. BGA … The term green algae are denoted to any green colored algae which are present in freshwater habitats.

Gerd Guenther/Science Photo Library/Getty Images. Euglenoids (Euglenophyta) These are about 800 species of unicellular algae. [19] This primary endosymbiosis event gave rise to three autotrophic clades with primary plastids: the green plants, the red algae and the glaucophytes. As their environment dries out, asexual V. carteri quickly die. They contain the chlorophyll a, b and the orange and the yellow pigments the carotenoids. [12], Green algae have chloroplasts that contain chlorophyll a and b, giving them a bright green color, as well as the accessory pigments beta carotene (red-orange) and xanthophylls (yellow) in stacked thylakoids. Edible types of green algae include sea lettuce, sea palm, and sea grapes. Instead, a 'raft' of microtubules, the phragmoplast, is formed from the mitotic spindle and cell division involves the use of this phragmoplast in the production of a cell plate. Other examples include Volvox, Gonium, and Cladophora, all of which occur in colonies. We may certainly talk of algae green do blue essay a piece of structured writing.
