Definition of rhizoid in English: rhizoidnoun ˈrʌɪzɔɪdˈraɪzɔɪd Botany A filamentous outgrowth or root hair on the underside of the thallus in some lower plants, especially mosses and liverworts, serving both to anchor the plant and (in terrestrial forms) to conduct water. Example sentencesExamples - The other end manifests an array of long, filamentous rhizoids that have the appearance, and apparently serve the same function, as root hairs.
- We defined above-ground biomass (standing crop) of mosses as the loose individual stems of mosses above the network of roots, rhizomes and rhizoids of the organic turf.
- We know that the plant forms structures called rhizoids that could produce new growth.
- The majority of apical fragments from these plots appeared to be in a state of ‘suspended activity’ as they retained their original color but failed to produce rhizoids or sprouts.
- It is likely that the rhizoids absorb water, but only because almost everything in a moss absorbs water.
Derivatives adjective Botany Yuan et al. restricted Baculiphyca to those clavate forms with rhizoidal holdfasts and thus differentiated it from Diaoyapolites, which has a globose holdfast according to Chen and Xiao. Example sentencesExamples - Baculiphyca taeniata was considered to differ from D. longiconoidalis on the basis of its rhizoidal rather than globose holdfast; however, the difference in holdfasts is probably preservational.
- The spherically symmetrical zygote then selects and elaborates an axis, visibly breaking symmetry by producing a rhizoidal bulge at about 10 h after fertilization.
- These include clavate ribbons with a rounded upper end and a somewhat pointed lower end, but devoid of any rhizoidal holdfast structures; such ribbons may be poorly preserved Baculiphyca taeniata.
- After harvesting, whole algae were extensively washed with natural seawater to remove any attached sand and the rhizoidal portions were removed to avoid microbial contamination in the following culture.
