| dbo:abstract | زويد: في علم النبات، زويد هي الخلايا التناسلية (أو الأمشاج) التي تمتلك سوطاً واحدا أو أكثر من سوط، وتكون قادرة على الحركة المستقلة. (ar) Σε πολλά από τα κατώτερα ζώα (κοράλλια, μέδουσες, κλπ.) η αναπαραγωγή γίνεται με δύο τρόπους: με αυγά και με εκβλαστήσεις που συνεπάγονται ή όχι αποχωρισμό από τον γονέα και που πολύ συχνά τα προϊόντα τους δε μοιάζουν καθόλου με εκείνα που προέρχονται από το αυγό. Οι τελευταίες αυτές μορφές, που φαινομενικά αποτελούν ιδιαίτερα άτομα, έχουν πάρει το όνομα ζωίδια (zoids). Να μη γίνεται σύγχυση με το ζωοειδές (zooid). (el) In botany, a zoid or zoïd /ˈzoʊ.ɪd/ is a reproductive cell that possesses one or more flagella, and is capable of independent movement. Zoid can refer to either an asexually reproductive spore or a sexually reproductive gamete. In sexually reproductive gametes, zoids can be either male or female depending on the species. For example, some brown alga (Phaeophyceae) reproduce by producing multi-flagellated male and female gametes that recombine to form the diploid sporangia. Zoids are primarily found in some protists, diatoms, green alga, brown alga, non-vascular plants, and a few vascular plants (ferns, cycads, and Ginkgo biloba). The most common classification group that produces zoids is the heterokonts or stramenopiles. These include green alga, brown alga, oomycetes, and some protists. The term is generally not used to describe motile, flagellated sperm found in animals. Zoid is also commonly confused for zooid which is a single organism that is part of a colonial animal. (en) Zooide (do grego zoeidés, «semelhante a animal»), ou mais raramente zóide, é a designação dada em botânica e em outros ramos das ciências biológicas às células reprodutivas especializadas (gâmetas e zigotos sensu lato) que apresentam motilidade através do uso de um ou mais flagelos, capazes por isso de movimento próprio e autónomo, quando produzidas por plantas ou algas. O termo não é geralmente usado para descrever os espermatozóides móveis flagelados encontrados em animais, embora seja comum o seu uso para designar os zoósporos assexuais dotados de motilidade encontrados em algas, fungos e protozoários. O termo «zooide» também é frequentemente confundido com zooide, um indivíduo que faça parte de um animal colonial. (pt) |
