Chloropicophyceae is a class of green algae in the division Chlorophyta that, along with Picocystophyceae, coincides with the traditional "prasinophyte clade VII".[1] Chloropicophyceae has a single order, Chloropicales with a single family, Chloropicaceae.
Description
[edit]Members of this class are coccoid green cells, with a diameter of 1.5–4 μm, found in marine waters, with one nucleus, one mitochondrion, and one chloroplast surrounded by two membranes, containing starch grain; their single chloroplast has chlorophylls a and b; they lack pyrenoid and flagella; and they have a layered cell wall. Their sexual reproduction is unknown.[1]
