大約 12 年之前,花粉穀粒發芽,產生慢慢地經過向發展中的 megagametophyte 的 nucellus 的薄的紗織品消化了它的方法的花粉管。在授粉後大約一年, 四個中生殖細胞-細胞男性的配偶體接受區分, 引起細胞的二個類型-一個不毛的細胞 (莖細胞) 和一個 spermatogenous 細胞 (身體細胞). 後來, spermatogenous 細胞分歧, 產生二個精液。 男性的配偶體, 或發芽花粉穀粒, 是現在成熟的。 取消哪一種子廠不形成 antheridia。
在授粉後 15 月,花粉管到達它放電許多的它的細胞質和它的兩個精液進入蛋細胞質 (圖 20-26) 的造卵器的蛋細胞。 一個精液核心以蛋核心聯合,而且另一個退化。 普遍,所有 archegonia 的蛋被施肥而且開始進入胚胎 (polyembryony 的現象) 之內發展。 只有一個胚胎通常完全發展, 但是在發芽之上的大約 3-4% 三個苗木。
在早的胚形成期間,細胞的四列在造卵器的下端的附近被生產。 每個在四個細胞中最上列 (哪一是, 列最遠形成 ovule 的 micropylar 結束) 開始形成一個胚胎。 同時地列的這四個細胞在胚胎,suspensor 細胞, 下面延長很大而且強迫穿過造卵器的牆壁四發展中的 embtyos 和進入女性的配偶體之內。 因此, polyembryony 的第二類型在松樹生命周期中被發現。 再一次,然而, 通常,胚胎的只有一個完全發展。 在胚形成期間,外殼進入一件種子外套之內發展。
松類種子是顯著的結構,因為它有一個二不同的雙重 sporophytic 的組合世代-種子外套 (和 nucellus 的剩餘) 和胚胎-和一 haploid gametophytic 世代 (圖 20-27). 配偶體視為食物預備品或有營養的薄紗織品。 胚胎有胚橋-根軸, 藉由 rootcap 和頂上的分裂組織在一端和一個頂上的分裂組織和一些 (通常八) 子葉或種子樹葉, 在另一個。外殼有三層,其中中央的層變成很難而且視為種子外面復蓋。

③ 英語翻譯英文的serendipity,應該怎麼翻中
沒有這個字,只有seahare這個字,意思是海兔。
海兔不是兔,是螺類的一種,海兔科海洋腹足類的統稱,又稱海蛞蝓。其頭上的兩對觸角突出如兔耳。海兔屬淺海生活的貝類。它是甲殼類軟體動物家族中的一個特殊的成員。它們的貝殼已經退化為內殼。背面有透明的薄薄的殼皮,殼皮一般呈白色,有珍珠光澤。
海兔是雌雄同體的生物,海底棲息,體裸露,雌雄兩個生殖孔間有卵精溝相連。海兔分布於世界暖海區域,中國暖海區也有出產。
海兔是科學家發現的第一種可生成植物色素葉綠素的動物。
海兔不是兔。海兔頭上的兩對觸角突出如兔耳,體光滑,或有許多突起。觸角分工明確,前面一對稍短,專管觸覺;後一對稍長,專管嗅覺。海兔在海底爬行時,後面那對觸角分開成「八」字形、向前斜伸著,嗅四周的氣味,休息時這對觸角立刻並攏,筆直向上,恰似兔子的兩只長耳朵。當它不動時,活像一隻蹲在地上豎著一對大耳朵的小白兔,因而最早被羅馬人稱為海兔。後被世人所公認,海兔因而得名。日本人稱它「雨虎」。
海兔的個體較小,一般體長僅10厘米,體重130克左右,身體呈卵圓形,運動時身體可變形。海兔並非哺乳動物,體外無皮毛。它屬於軟體動物門腹足類動物。但又與常見的腹足類動物(如鮑、田螺、蝸牛)不同:海兔沒有石灰質的外殼,而是退化成一層薄而透明、無螺旋的角質殼,被埋在背部外套膜下,從外表根本看不到,而是在背面由一層薄而半透明的角質膜覆蓋著身體(這一點和蛞蝓相同,故又名海蛞蝓),薄薄的殼皮一般呈白色,有珍珠光澤。
海兔的足相當寬,足葉兩側發達,足的後側向背部延伸。平時,海兔用足在海灘或水下爬行,並借足的運動作短距離游泳。
海蛞蝓是雌雄同體的生物,海底棲息,體裸露,雌雄兩個生殖孔間有卵精溝相連。
海兔還是重要的神經生理學實驗動物。2000年諾貝爾獎獲得者坎德爾德在《追尋記憶的痕跡:2000年諾貝爾獎得主坎德爾德探索之旅》中有對海兔的詳細描述,其由於海兔的巨大的、便於監測的腹神經節而選中海兔作為研究對象,進而發現了經典學習模型的細胞原理。
中國的海兔已定名的有21種。海兔個體較小,一般體長僅10厘米,體重130克左右。海兔不是哺乳動物,體外無皮毛。它屬於軟體動物門腹足類動物。但又與常見的腹足類動物不同:沒有石灰質的外殼,只有一層薄而半透明的角質膜覆蓋著身體。體呈卵圓形,運動時身體可變形。頭上一前一後,長有二對觸角。
生活在美國新英格蘭地區和加拿大的鹽鹼灘的一種通體碧綠的海蛞蝓可以進行光合作用,是人類發現的第一種可生成植物色素葉綠素的動物。除了生成葉綠素所必需的基因外,它們還「竊取」了稱為葉綠體的細胞器,利用其實施光合作用。同植物一樣,海蛞蝓的葉綠體藉助葉綠素將陽光轉化為能量,因此就沒了通過吃食物以獲取能量的必要。研究人員採用放射性示蹤劑以確保海蛞蝓確實是通過自身力量生成葉綠素,而不是從藻類身上竊取的這種現成的色素。事實上,海蛞蝓完全吸收了這種遺傳物質,將其遺傳給下一代。這些海蛞蝓的後代同樣可以生成自己的葉綠素,不過,在吃掉足夠的藻類以獲取必要的葉綠體之前,它們還不能進行光合作用。科學家迄今尚不清楚這種動物是如何盜用所需要的基因的。
母音字母組合ea在單字里發長母音/i/的音,發音時,舌端靠近下齒,舌前部抬得很高,但不接觸上顎,不發生任何摩擦,牙床接近合,唇形扁平,/i/這個音出現在字首、字中和字尾位置,如:

⑨ 農夫山泉「蟲卵」事件 「蟲卵」英語怎麼說
蟲卵的英文為egg。
由卵巢內大型特化的生殖細胞發育而成。大多數蟲種的受精卵產生後,胚胎開始發育,最後孵化出幼體昆蟲。隨著發育階段的不同,卵對環境的適應能力及對殺蟲劑的敏感性不同。
當人畜與疫水接觸時,尾蚴借其頭腺分泌的溶組織酶作用和其肌肉收縮的機械運動,很快鑽入皮膚(或粘膜)並脫去尾部變為童蟲。童蟲經小靜脈或淋巴管進入血液循環,再經右心而到達肺。以後由肺的毛細血管經肺靜脈而入大循環向全身散布。只有進入腸系膜靜脈的童蟲,才能繼續發育為成蟲,其餘多在途中夭折。通常在感染尾蚴後3周左右即可發育為成蟲,雌雄成蟲交配後即可產卵。蟲卵隨門靜脈血流順流到肝,或逆流入腸壁而沉著在組織內,約經11天左右逐漸發育為成熟蟲卵,內含毛蚴。腸壁內的蟲卵可破壞腸粘膜而進入腸腔,並隨糞便排出體外,再重演生活周期。蟲卵在組織內的壽命約為21天左右。雌雄合抱的成蟲在人體內的壽命一般為3~4年。
蟲卵沉著所引起的損害是最主要的病變,蟲卵除主要沉著於乙狀結腸和直腸壁以及肝外,也常見於回腸末段、闌尾及升結腸等處。肺、腦等其他器官有時也可見到。未成熟的蟲卵所引起的病變輕微;含毛蚴的成熟蟲卵往往引起蟲卵結節形成。按其病變發展過程可分為急性蟲卵結節和慢性蟲卵結節兩種。
母音字母e在重讀閉音節里一般發短母音/ɛ/的音,發音時,舌端靠近下齒,舌前部抬高,舌位適中,不接觸上顎,沒有摩擦,牙床介於半合半開之間,唇形扁平。這個音出現在字首、字中,但很少出現在字尾的位置,如:
egg 雞蛋
well 井
red 紅的
pen 鋼筆
hen 母雞
net 網路
bed 床
bell 鈴鐺
