Biology:Palmophyllophyceae

From HandWiki

The Palmophyllophyceae are a class of green algae consisting of the Palmophyllales and Prasinococcales.[1]

Palmophyllophyceae consists of planktonic, single cells or colonies of cells, or cells embedded in a gelatinous, macroscopic matrix. Cells are spherical or subspherical, surrounded by a cell wall. The cell contains a single cup-shaped chloroplast enclosing a mitochondrion, nucleus, and large Golgi body. The chloroplast has two membranes and may have a pyrenoid. The chloroplast contains chlorophyll a and b.[1]

It belongs to Prasinodermophyta, a group that – according to Li et al.'s phylogenetic analyses – is basal to the rest of the Viridiplantae (that is, the group of all green algae, from which land plants evolved, also known as "green plants").[2]
