Viridiplantae (lit. ' green plants ' ; kingdom Plantae sensu stricto ) [ 6 ] is a clade of around 450,000–500,000 species of eukaryotic organisms, most of which obtain their energy by photosynthesis .
Chlorophyte microalgae are a valuable source of biofuel and various chemicals and products in industrial amounts, such as carotenoids, vitamins and unsaturated fatty acids. The genus Botryococcus is an efficient producer of hydrocarbons, which are converted into biodiesel .
Green algae are often classified with their embryophyte descendants in the green plant clade Viridiplantae (or Chlorobionta). Viridiplantae, together with red algae and glaucophyte algae, form the supergroup Primoplantae, also known as Archaeplastida or Plantae sensu lato. The ancestral green alga was a unicellular flagellate. [20]

[4] [5] [6] Together with the red algae (Rhodophyta) and the green algae plus land plants (Viridiplantae or Chloroplastida), they form the Archaeplastida. The glaucophytes are of interest to biologists studying the evolution of chloroplasts as they may be similar to the original algal type that led to the red algae and green plants, i.e ...

Picochlorum oklahomense is a species of coccoid chlorophyte algae, the type species of its genus. It is broadly halotolerant, small, asexual and lacks chlorophyll b. [1] The author of the name spelt the specific epithet "oklahomensis".
The chlorophyte and charophyte green algae and the embryophytes or land plants form a clade called the green plants or Viridiplantae, that is united among other things by the absence of phycobilins, the presence of chlorophyll a and chlorophyll b, cellulose in the cell wall and the use of starch, stored in the plastids, as a storage polysaccharide.
