内皮层

Finally, cell wall degraded and aggregated together, which results in gas spaces formation in a radial direction.3. Aerenchyma formation appeared to be a form of nonapoptotic programmed cell death in the middle of root cortex.

3稻根内通气组织形成的实质很可能是位于内皮层和外皮层之间的皮层细胞发生非凋亡的程序化细胞死亡形成的。

A plant tissue characteristic of the roots, located between the endodermis and phloem.

内皮层皮层的最内层，在根、茎的导管组织周围形成一道叶鞘

The inner layer of the cortex differentiates into the endodermis.

皮层的内层分化为内皮层。

The intercellular spaces of parenchyma cells close to exodermis and endodermis were smaller, but that in the cortex were larger.

土培根中靠近外皮层和内皮层的薄壁细胞的胞间隙小，皮层薄壁细胞的胞间隙较大。

Effect of light on formation of endodermis in stem of broad bean seedling was studied by measuring the levels of endogenous antioxidants and certain key enzymes postulated to be involved in suberization.

幼苗为材料，结合不同的光强及黑暗对茎中内皮层形成的影响，对参与栓化作用有关的酶活性及内源抗氧化物质的含量进行了测定，并讨论了光对内皮层形成的调节机制。

Formation of endodermis was inhibited in stem grown under high intensity light and induced under low intensity light and in the dark.

实验结果表明，高光强抑制茎中内皮层形成，而低光强和黑暗诱导茎中形成内皮层。

Epidermis, cortex, endodermis, stale can be observed from the surface of a root to the center.

从根的横切面从外向根内观察，可分为表皮、皮层、内皮层和中柱这4个部分

The cortical cells had thin walls and mitochondrium, and nucleus wassurrounded by chloroplasts, and vesicles were next to cell plasmalemma. However, cellwalls of velamen, cortex and exodermis in the mycorrhiza of D. nobile had ring orpapillary thickenings in many cases. The hyphae were surrounded by moremitochondria and vesicles of plant, and the hyphae were digested and their structure waschanged at last. The cell wall of endodermis also had typical ring thickenings, and manysieve orifices in sieve tube elements of phloem were covered by callose, while therewere liaison cords in a few sieve orifices.

金钗石斛菌根的根被细胞的细胞壁多处出现环形圈，外皮层细胞壁加厚，木质化，也有环形圈存在，皮层细胞细胞壁多角形明显，加厚，皮层细胞中存在被消化、失去结构的真菌菌丝，在菌丝周围有较多的线粒体、小泡，内皮层细胞的细胞壁呈现的典型的加厚及木质化环形圈，韧皮部筛管的筛板结构，绝大多数筛孔已为胼胝质所覆盖，仅个别筛孔中还存在连络索。

Pericycle The parenchymatous layer of cells that lies within the endodermis,forming the outermost part of the stele.

中柱鞘：位于内皮层以内紧挨内皮层的一层或几层薄壁细胞，形成中柱的最外部分。

The water content of external layer of root xylem of Kalidium foliatum is highest. In the range of root diameter from 0.3cm to 0.5cm,the most roots diameter are between 0.3cm and 0.5cm.

盐爪爪根的皮层含水量在径级为0.3－0.5cm范围内最高，大于0.5cm含水量反呈下降，而盐节木根径级在0.5－0.6cm范围内皮层和木质部含水量均最高，这可能是盐爪爪和盐节木根系径级分别多集中在0.3－0.5cm和0.5－0.6范围内的原因之一。

Fancy gold-plated dangling earrings with facetted White Opal crystals.

花式镀金悬垂耳环与facetted白欧泊水晶。

This essay chooses the study aim from biology teachers in middle school in Shi Jiazhuang which tells us that most of the middle school biology teachers in Shi Jiazhuang have the"burnout", lower successfulness, individualize.

本文选取石家庄市初中生物教师作为研究对象，运用问卷调查的方法对石家庄市初中生物教师职业倦怠的现状进行调查，调查结果发现，石家庄市初中生物教师这一群体普遍存在职业倦怠，情感枯竭程度偏高，成就感偏低，去个性化程度最为严重。
