Definition of coenocyte in English: coenocytenounˈsiːnəʊsʌɪtˈsēnəˌsīt Botany A body of algal or fungal cytoplasm containing several nuclei, enclosed in a single membrane. Example sentencesExamples - These coenocytes are tubular multinucleated filaments with no internal partitioning into cells.
- If the ‘branched’ botuliform cells derived from a branched filamentous coenocyte, then there is also a reasonable case for inferring the presence of the form-genus Palaeovaucheria.
- Unlike the secondary division of a coenocyte that yields the linear arrays of cells, this variant appears to represent a growing structure caught at various stages of its development.
- One characteristic feature of the majority of syncytia and coenocytes is that their nuclei are regularly spaced within the cytoplasm.
- The mycelia are large coenocytes with many nuclei and can therefore be heterokaryotic.
Derivatives adjectivesiːnəʊˈsɪtɪk Botany Among extant plant protists, this type of siphonous or coenocytic architecture appears to be limited to the chlorophyte and chrysophyte algae. Example sentencesExamples - Besides the already mentioned yeast spores, a good examples of a coenocytic plant is the multinucleate algae.
- In multinucleate coenocytic green algae, very large nuclear genomes have a role in maintaining nucleus/cytoplasm ‘domains’.
- Some are unicellular, some coenocytic, and still others produce a mycelium much like other fungi.
- The cell content is readily released by gently squeezing the segments of the coenocytic cellular organization.
