pyrenoid

py·re·noid

P0685600 (pī-rē′noid′, pī′rə-)n. A proteinaceous structure found within the chloroplast of certain algae and hornwort bryophytes. It is thought to be a site where carbon is concentrated.

[New Latin pȳrēna, fruit stone; see pyrene¹ + -oid.]

pyrenoid

(ˈpaɪrəˌnɔɪd) n (Biochemistry) any of various small protein granules that occur in certain algae, mosses, and protozoans and are involved in the synthesis of starch[C19: from pyrene² + -oid]

Pyrenoid

a cell organelle of many algae and of Hepaticae (mosses) of the order Anthocerotales. Pyrenoids, which are rounded or angular in outline, are located in or on the chloroplast. They are always closely associated with the chloroplast and serve as the site of starch formation. The size and number of pyrenoids may change with the age of the cell. The pyrenoid consists of a central protein body—the stroma—and a starchy covering (some pyrenoids lack this covering). The stroma of the pyrenoid, like that of the chloroplast, is finely granular; however, its consistency is more solid. It has embedded lamellae consisting of a continuation of more or less reduced lamellar system of the chloroplast. New pyrenoids arise as new formations or as a result of binary fission or fragmentation. The presence or absence of pyrenoids is a taxonomic characteristic.

pyrenoid

[′pir·ə‚nȯid] (botany) A colorless body found within the chromatophore of certain algae; a center for starch formation and storage.

pyrenoid

py·re·noid

(pī'rĕ-noyd), One of the minute luminous bodies sometimes visualized in the chromatophores of some protozoa, such as Euglena viridis. [G. pyrēn, pit of a fruit, + eidos, resemblance]

pyrenoid

a region of starch formation found in the CHLOROPLASTS of various algae, for example, Spirogyra, Chlamydomonas.
