假根

A division of nonflowering plants characterized by rhizoids rather than true roots and having little or no organized vascular tissue and showing alternation of generations between gamete-bearing forms and spore-bearing forms; comprises true mosses and liverworts and hornworts.

In previous management experience, it was found that a new desert governance is formed through microbial mucus conglutinate sand, or by algae, lichens and the moss Jiagen tied up and the formation of biological tie skin, a protective network to start, it can operate effectively constraining the flow, and thus play a dune-fixing role.

结合以前的治理经验，人们发现了一种新的沙漠治理方法，就是通过微生物形成的黏液粘连沙粒，或者被藻类、地衣和苔藓的假根捆绑起来，形成生物结皮，形成接近细沙的防护网，它能有效束缚沙粒流动，从而起到固沙作用。

Ciliata consists of two elements, the robust and short filamentous chloronema which is composed of 4~6 oblate cells and the thin and long caulonema like osier on which there are many clavae of 2~5 cells.

丝状绿丝体一般由4~6个短粗柱状细胞组成；而轴丝体则是由多数细长柱形细胞构成，其上间隔分布有2~5个细胞组成的棒状体，初生假根有或者无。

The effects of different concentrations of arsenic on spore germination and rhizoid and prothallium growth of Pteris vittata under aseptic condition were studied.

研究无菌条件下不同浓度砷对蜈蚣草的孢子萌发、假根和原叶体生长发育的影响。

The fern spore, the original cell of the gametophyte, carries out asymmetrical mitosis to produce a large cell and a small cell. The small cell geminates to a rhizoid by tip growth, and the large cell further divides and develops to become a prothallus.

蕨类植物孢子作为配子体的原始细胞，通过不对称的有丝分裂产生一大一小两个细胞，小细胞萌发出极性生长的假根，大细胞继续分裂发育为原叶体。

Rhizoid A unicellular rootlike structure found in certain algae and in the gametophyte generation of the bryophytes and some ferns.

假根：在一些藻类、苔藓植物和裸子植物配子体中存在的由单个细胞形成的类似根的结构。

The enzymes break down the food to simple diffusible compounds which are absorbed into the rhizoids by diffusion and active transport.

假根必泌酵素将食物分解为简单的可扩散化合物，然后透过扩散及主动运输将食物吸进假根。

Hyphae in certain species may become specialized to form rhizoids, which serve as rootlike anchors, or they may become thefeeding structures known as haustoria.

某些种类的菌丝可能特化形成假根，具有根样的固定作用，或者他们成为饲喂结构称吸器。

"Superficially resembling higher plants, stoneworts have rootlike and stemlike structures, as well as whorls of branches at regular intervals."

轮藻的外观似高等植物︰具根状假根和按一定间隔出现的轮生分枝，直立的圆柱形中轴外围以由小细胞组成的鞘

Since there are many branched rhizoids, thus the surface area can be greatly increased for both digestion and absorption of nutrients.

因为有许多分生假根，消化和吸收营养的表面积可大大地增加。
