This may be due to hydrolytic chelating, precipitation and the sediment or hydrobioes attachment, absorption etc. The honewort had stronger ability of accumulating La because of its large leaf surface that could attach La. The accumulating ability of snail and fish to La was relatively weaker but some organs of them had higher contents of La especially in the intestines, shell of snail, and in gill, internal organs, scales, head, bone of fish, rare in muscle. The total accumulating quantities of La in each component of simulated aquatic ecosystem were a decreasing order of: sediment >honewort>snail>fish, and the sequence of bio-concentration facter was as follows: honewort>snail>fish.
2金鱼藻对La有较强的富集能力,主要通过枝叶表面吸附、吸收而富集;螺蛳对La也有一定的富集,并主要分布于肠、壳中,螺头中积累相对较少;草鱼对La的富集能力相对较弱,进入鱼体的La主要集中在鳃、内脏、鳞及头、骨中,肌肉中积累量较少;按质量计,稀土元素La在模拟水生态系统各部分中的积累量依次为:底泥>金鱼藻>螺蛳>草鱼;各水生生物对稀土La的生物富集因子依次为:金鱼藻>螺蛳>草鱼。

The classic example is the ear ossicles of mammals, which we know from palaeontological and embryological studies originated in the upper and lower jaws and the hyoid of their Synapsid ancestors, and further back still were part of the gill arches of early fish.

Under light microscope, on H-E stain section, four types cells can be distinguish: cells with weak basophilic fibrillar elements; cells with acidophilic granular substance; cells with strong basophilic fibrillar elements and ciliated cells. In the basal lamina region under gland epithelium, there are a few connective tissue; Surface view of the hypobranchial gland could be see by scanning electron microscope, there are cilia and different kinds of secretions distributed. Ultrastructure of the hypobranchial gland could be understand by transmission electron microscope, supporting cells, sensory cells and seven types gland cell were observed to form the glandular epithelium; cells with much rough endoplasmic reticulum,smooth muscle fiber and nerve endings were found beneath glandular epithelium, among basal lamina region.
光镜下H-E染色切片中腺上皮区仅可以区分出四种类型的细胞:弱嗜碱性纤维样细胞、强嗜碱性纤维样细胞、嗜酸性颗粒分泌细胞和纤毛细胞等;腺上皮下的基底膜区有少量结缔组织存在;扫描电镜下可以观察到鳃下腺表面的纤毛及腺细胞的分泌物等情况;透射电镜下观察到腺上皮中有支持细胞、感觉细胞和7种类型的腺细胞;近基底膜区观察到富含粗面内质网的细胞;基底膜间为薄层疏松结缔组织,内含肌细胞及神经末梢等结构。
