Abstract
The sequence of somatic phases in the life history of the red alga Polysiphonia denudata has been determined in unialgal culture, using supplemented seawater media. Tetraspores gave rise to sexual plants bearing either antheridia or carpogonia in 50 days. Fertilization occurred within 1 week and the fertilized carpogonium developed to produce the mature carposporophytic phase in approximately another week. Carpospores formed by the carposporophyte germinated to produce the tetrasporangium-bearing phase, which released tetraspores in 44 days, thus completing the life history in 3 1/2 months. No deviations from this pattern have so far been observed.This publication has 2 references indexed in Scilit:
