Amphioxus , an existing animal that belongs to the phylum chordata , subphyla cephalochordata , is always regarded as the invertebrates which is the nearest to the vertebrates . it has great sense on the research of how the vertebrates develop from invertebrates 長久以來,文昌魚一直被認為是現存的與脊椎動物親緣關系最近的無脊椎動物( stokeandholland , 1998 ; zhangetal . , 2001 ) ,在脊椎動物如何由無脊椎動物進化而來這一著名的生物學難題中占據重要的位置。

Today the grouping is considered to be artificial and many taxonomists support the five kingdoms classification whereby the bacteria and fungi are both assigned to separate kingdoms , while algae and protozoans constitute various phyla of the kingdom protoctista 如今這種分類被認為是人為化的,而且許多分類學家支持五界分類系統,在該系統中細菌和真菌分別為獨立的界,而藻類和原生動物構成原生生物不同的門。

Cycadophyta ( cycads ) a phylum of cone - bearing gymnosperms ( about 75 living species ) with palmlike compound leaves and special coralloid roots at or near the ground surface , which contain symbiotic nitrogen - fixing cyanobacteria 蘇鐵綱(蘇鐵類植物) :包含球果的一類裸子植物(現存種大約有75種) ,它們具有掌狀的復葉,在近地面處有特殊的珊瑚狀的根,根內含有共生的固氮藍細菌。

Hepatophyta ( marchantiopsida ; liverworts ) a phylum containing leafy and prostrate thallose forms , commonly known as liverworts , thallose liverworts are prostrate and dichotomously branched with thalli several cells thick 苔類植物門(地錢綱,苔類) :是一門包括多葉的或匍匐葉狀體類型的植物,如通常所說的苔類。

A unicellular protoctist of the phylum ciliophora , whose members are usually covered in short undulipodia ( cilia ) and have two different kinds of nuclei , micronuclei and macronuclei 2纖毛蟲:纖毛蟲綱的一類原生單細胞生物。該類生物具有短的纖毛,還具有兩個細胞核,一個是大核,另一個是小核。

On the other hand , because of the big quantity of the arthropod fossils , arthropoda is still the phylum which is researched most frequently and deeply 但另一方面,由于節肢動物化石的產量很大,所以它依然是研究最多和最深入的一個化石門類。就目前狀況而言,將待研究的其它節肢動物還很多。

Jianshan section of haikou was measured and described and some monospecific layers were reported in chapter i . 2 . several phyla of introverts are briefly introduced in chapter ii . 3 第三章對澄江動物群化石中的蠕蟲化石的保存、埋藏、生態等方面作了進一步的研究探討。

Actually , the term coral is much broader and refers to most of the animals in the class anthozoa and a few animals in the class hydrozoa of the phylum cnidaria 其實珊瑚一詞所指的動物甚多,包括大多數屬珊瑚蟲綱及數動屬水螅蟲綱的刺胞動物。珊瑚是固著的動物,不能移動。

In the modern five kingdoms classification , certain funguslike organisms that were previously considered to be fungi , are now assigned to phyla in the kingdom protoctista 在現代五界分類系統中,一些霉菌有機體,以前被認為是真菌,現在將其分為原生生物界中的一門。

Formerly , the bryophyta also included the liverworts and hornworts , which in the five kingdoms classification are now placed in separate phyla ( hepatophyta and anthocerophyta ) 孢子萌發產生一個絲狀的單倍體,將來可以發育為芽體,進而形成整個植株。

There are three main phyla of fungi , based on the nature of their fruiting structures : the zygomycota , ascomycota , and basidiomycota 真菌根據其“果實” (子實體譯者注)結構特征分為三大門類:接合菌類、子囊菌類和擔子菌類。

Cyanobacteria a phylum of eubacteria containing the blue - green bacteria ( formerly called blue - green algae ) and the green bacteria ( chloroxybacteria ) 藍細菌:真細菌中的一門,包括藍綠細菌(以前被稱為藍綠藻)和綠細菌。

Desmids a group of green algae of the phylum gamophyta that are basically single - celled but in some species form filamentous or irregular colonies 鼓藻:綠藻門鼓藻科的一類植物。藻體為單細胞或群體,群體呈球狀或絲狀。

Actually , the term coral is much broader and refers to most of the animals in the class hydrozoa of the phylum cnidaria 其實珊瑚一詞所指的動物甚多,包括大多數屬珊瑚蟲綱及數動屬水螅蟲綱的刺胞動物。

Psilophyta ( whisk ferns ) in the five kingdoms classification scheme , a phylum of vascular seedless plants , the whisk ferns 裸蕨植物門(松葉蕨) :在五界分類系統中,一門不產生種子的維管植物,松葉蕨。

Charophyceae a class of the chlorophyta ( green algae ) that includes the stoneworts , formerly placed in a separate phylum charophyta 輪藻綱:綠藻門中的一綱,以前列為獨立的輪藻門。

Angiosperms the flowering plants constituting by far the largest phylum ( anthophyta or angiospermophyta ) of vascular seed plants 被子植物:由顯花植物組成的最大的一門維管種子植物。

Actinobacteria ( ray fungi ; actinomycetes ) a phylum of eubacteria that contains the true actinobacteria and the coryneform bacteria 放線菌:一門真細菌包含真放線菌以及棒狀桿菌。

Five kingdoms classification a classification system that recognizes five kingdoms containing at least 96 phyla 五界分類系統;指認為生物界分為五界,并至少含有96門的分類系統。
