Examples

  • Vascular bundle sheath
    維管束鞘
  • Palisade tissue is rich in saliferous vacuoles , while vascular bundle sheath is obvious
    柵欄組織富含含鹽液泡泡，維管束鞘明顯。
  • Bundle sheath the ring of parenchymatous or sclerenchymatous tissue , usually one cell thick , that surrounds the vascular bundle in an angiosperm leaf
    維管束鞘：在被子植物葉中，圍繞維管束的通常是一層薄壁或厚壁細(xì)胞。
  • There are 2 - 3 layers of long - column - shaped palisade tissue under the upper epidermis , and there are a great number of mechanical tissues which made up of vascular bundle sheath
    上表皮下方有2 - 3層長(zhǎng)柱形的柵欄組織，在主脈大側(cè)脈外方具有由大量機(jī)械組織組成的束帽或束鞘。
  • The cells of the bundle sheath that surround the vascular tissues are large and contain specialized elongated chloroplasts that do not contain grana , but form starch grains
    它的特點(diǎn)為：圍繞在維管組織外層的維管束薄壁細(xì)胞較大，并含有較大的葉綠體，這些葉綠體中不含基粒，但形成淀粉粒。
  • In these chloroplasts carbon dioxide combines with phosphoenolpyruvate to form oxaloacetic acid , which is transported to the bundle sheath cells , where the carbon dioxide is released , then fixed by the enzyme ribulose bisphosphate carboxylase to form glycerate 3 - phosphate , the first step in the calvin cycle
    在葉肉細(xì)胞的葉綠體中二氧化碳與磷酸烯醇丙酮酸結(jié)合形成草酰乙酸，后被運(yùn)到鄰近的維管束鞘細(xì)胞，在那里二氧化碳被釋放，后被核酮糖二磷酸羧化酶固定形成3磷酸甘油酸，這是卡爾文的循環(huán)第一步。

    實(shí)驗(yàn)研究的兩種菊科（ compositae ）植物（準(zhǔn)噶爾沙蒿（ artemisiasongaricaschrenk ）和沙漠絹蒿（ seriphidiumsantolinum ( schrenk ) poljak . ） ） ，形態(tài)解剖方面的變化表現(xiàn)為：隨日齡增加，根長(zhǎng)/株高比值日益增大；根系逐漸發(fā)達(dá)；體積與葉面積比逐漸增大；表皮細(xì)胞體積變?。唤琴|(zhì)層增厚；根外部出現(xiàn)加厚的木栓層；氣孔下陷；葉、莖部的表皮毛密布，柵欄組織日益發(fā)達(dá)；而細(xì)胞間隙日漸變?。缓＞d組織逐漸消失；葉面結(jié)構(gòu)常為典型旱生結(jié)構(gòu)? ?等葉面；晶細(xì)胞及纖維細(xì)胞數(shù)目增多；輸導(dǎo)組織、機(jī)械組織日漸發(fā)達(dá)；具有維管束鞘等等。

[ conclusion ] the distribution of anthraquinone compounds in the stem was of multilocus
    結(jié)果隨著莖的不斷成熟，在莖的表皮、近表皮的1 ~ 2層皮層細(xì)胞及較內(nèi)部皮層中，不同程度地增加貯藏和積累了一定數(shù)量的蒽醌類化合物，成為莖外部貯藏和積累蒽醌共化合物的主要結(jié)構(gòu)部位成熱莖大型維管束的維管束鞘、初生韌皮部、初生木質(zhì)部等組織和髓射線細(xì)胞分布了比幼莖多的蒽醌類化合物。
