The tracheid is derived from a single cell and can be regarded as the basic cell type of xylem tissue. It takes the form of an elongated water-conducting cell, with a lignified and variously thickened and pitted cell wall (Fig. 42.6A). At maturity it is a dead element. The pits are ...

The polymer lignin is deposited forming a secondary cell wall. The xylem vessels, though, have thinner secondary walls than the tracheids. Then, both of them form pits on their lateral walls. The xylem vessel is a series of cells called vessel members (or vessel elements), each with a ...
8.The early formed secondary xylem was characterized by a large number of wood fiber cells with non woody cell wall. 早期生成的次生木质部以细胞壁尚未木质化的木纤维细胞数量居多为特征。 9.In older stems, only the most recent rings of xylem participate in the transport of materials. These mak...
Xylem is composed of various kinds of cells, living or nonliving. The structure of these cells differs in their functions, but characteristically all have a rigid and enduring cell wall that is well preserved in fossils. In terms of their functions, the kinds of cells in xylem are those ...
Both of them form a secondary cell wall in between the primary cell wall and the plasma membrane that is lignified. The most common patterns of secondary cell wall thickenings are annular, spiral, scalriform, reticular, and pitted. However, the xylem vessels have thinner secondary walls. Both...
NAC SECONDARY WALL THICKENING PROMOTING FACTOR1 (NST1), NST2, and SECONDARY WALL-ASSOCIATED NAC DOMAIN PROTEIN1 (SND1), which belong to the subclade that is most similar to the VND family, are master regulators of xylem fiber cell differentiation (Fig. 3) (Ko, Yang, Park, Lerouxel, &...
The plant cell is composed of a cell wall, cell membrane, vesicles, ribosome, nucleus, cytoplasm, peroxisome, endoplasmic reticulum, Golgi vesicles, vacuoles and other basic elements. The organelles of the cell work in a union that results in the growth and development of plants. Nutrients ...
13. In the transection section, the area of secondary phloem is much larger than secondaryxylem. 在横切面上,次生韧皮部的面积比次生木质部大得多。 youdao 14. Multiple end wall and lateral-wall perforation plates were also observed in the secondaryxylem. ...
