3 Terms and definitions
The following terms and definitions apply to this document.
3.1
Thallus
The gametophyte generation is formed by the germination of conchospores and monospores.
Note. Objects of cultivation and harvest.
3.2
Conchocelis
The sporophyte generation is formed by the germination of fruit spores.
Note. It is divided into free filaments and shell filaments, which are the objects of seedling cultivation in the process of germplasm preservation and cultivation respectively.
3.3
carpospore
The thallus vegetative cells develop and transform into fruit cells, which, after fertilization, divide to form fruit spore sacs containing multiple cells and release spores.
3.4
conchospore
The filamentous algae filaments grow and develop into sporangium branches. After maturity, each cell divides once (bisection) to form conchospores.
Ascus, the released spores.
3.5
Archeospore
The thallus vegetative cells transform into monosporangium, each of which produces individual spores that are released.
Note. The single spore is haploid and germinates directly to grow into a thallus, which is the asexual reproductive spore of Porphyra yezoensis.
