The outer tangential wall of no - nodules legume plants epidermal cells is thicker and darker than that of nodule legume plants 非結(jié)瘤豆科植物的根表皮細(xì)胞外切向壁的厚度比結(jié)瘤豆科植物的要厚,顏色也較深。
Rays entirely parenchymatous , uni - serate ; horizontal and tangential walls of ray cells smooth and thin . cross - field pitting taxodoid with 1 - 4 pits 木射線單列,全由射線薄壁細(xì)胞組成;射線細(xì)胞水平壁薄,紋孔缺乏,端壁平滑。
It is clear that the inner tangential wall of the basal cell is tightly related with the outer tangential wall of 4 - 5transfer cells which have been considered a part of the extent of vascular bundle 基細(xì)胞內(nèi)切向壁與4 ? 5個傳遞細(xì)胞外切向壁緊密相連。紫穗槐同時以聚鹽和泌鹽兩種方式抗鹽。
The secondary sculpture is formed by the outgrowth of the outer tangential wall of the epidermal cell , and this kind of protuberance always occurs in the adjoining cells , which makes the laminar protuberances 這些突起是由雌性生殖單位外蓋被表皮細(xì)胞的外壁向外突出形成,這種突出生長常常在相鄰細(xì)胞之間同時發(fā)生,因此,出現(xiàn)片層狀構(gòu)造。
