Pyrenoids are sub-cellular phase-separated micro-compartments found in chloroplasts of many algae, and in a single group of land plants, the hornworts...

and traditionally has been distinguished mainly through the absence of a pyrenoid. Species of Chloromonas occupy a variety of habitats, including soil, temporary...

Starch can also accumulate around the pyrenoids when CO2 is scarce. Pyrenoids can divide to form new pyrenoids, or be produced "de novo". Thylakoids (sometimes...

of the monoplastidic species, a cellular structure called a pyrenoid is absent. The pyrenoid is a liquid-like organelle which enables a more efficient photosynthesis...

single chloroplast is present, filling nearly the entire cell; it lacks a pyrenoid. It is commonly used as a bioindicator species to assess the levels of...

this genus is characterized by its unique lobed chloroplast that lacks a pyrenoid, differentiating it from other unicellular red algae. It has drawn interest...

presence of pyrenoids is used as an identifying feature of the genus, separating it from other euglenoids, such as Lepocinclis and Phacus. Pyrenoids may be...
