CHLOROPLAST STRUCTURE OF THE CRYPTOPHYCEAE
Open accessAbstract
Selective extraction and morphological evidence indicate that the phycobiliproteins in three Cryptophyceaen algae (Chroomonas, Rhodomonas, and Cryptomonas) are contained within intrathylakoidal spaces and are not on the stromal side of the lamellae as in the red and blue-green algae. Furthermore, no discrete phycobilisome-type aggregates have thus far been observed in the Cryptophyceae. Structurally, although not necessarily functionally, this is a radical difference. The width of the intrathylakoidal spaces can vary but is generally about 200–300 A. While the thylakoid membranes are usually closely aligned, grana-type fusions do not occur. In Chroomonas these membranes evidence an extensive periodic display with a spacing on the order of 140–160 A. This periodicity is restricted to the membranes and has not been observed in the electron-opaque intrathylakoidal matrix.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
