Abstract
A culture study of the morphology, cytology and life cycle of Prasiola meridionalis was conducted. The alga was grown successfully in Provasoli's culture medium (1958) at a temperature of 5°C, and alternate periods of eight hours of light and sixteen hours of darkness. In culture, gametes are liberated only when mature reproductive or fruiting thalli are first illuminated for two hours with fluorescent light and then kept in the dark for several hours at temperatures of 3°- 5°C. The results of the study have indicated that the life cycle presents a dimorphic alternation of generations. The gametophytic tissue and gametes represent the haploid generation, and the sporophytic tissue and zygote the diploid generation. Meiosis is intermediate in the life cycle, occurring in the adult sporophytic cells. Sixteen chromosomes were observed in the diploid cells, zygote, aplanospores and somatic cells. Sexual reproduction is oogamous. The bi-flagellate micro-gamete is smaller than the macro-gamete which has no flagella. Asexual reproduction is accomplished by germination of aplanospores. Thalli which develop from germination of aplanospores and from zygotes appear the same morphologically.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
