解析 初级细胞壁与次级细胞壁这两种细胞壁表明了细胞的不同成熟阶段。初级细胞壁包围着正在生长的植物细胞,且为容纳进一步生长可以有一定程度的伸张。次级细胞壁发生于更为成熟的植物细胞,也更坚硬。它们较初级细胞壁含有更多的纤维素。次级细胞壁是更强的支撑结构。

Main Cell: A core Cell or Battery is one that can be easily charged after a single use, and is discarded after discharge. These Cells are not charged because the electrode reaction occurs only once and after prolonged use the batteries die and cannot be reused. Secondary Cell: The Secondary...

(General Physics) an electric cell that generates an electromotive force by the direct and usually irreversible conversion of chemical energy into electrical energy. It cannot be recharged efficiently by an electric current. Also called:voltaic cellComparesecondary cell ...
Both cell lines and primary cells have been investigated using the in vitro PDMS microfluidic chamber platforms28,33. Although the rapid proliferation of cell lines allows an ease of culture maintenance with low cell death rates, their genetic, phenotypic, structural, and functional characteristics ...
6.1.9 Cell-LEACH In Cell-Leach, the clusters are portioned in the form of various cells, and the cells are controlled by the cell head in each cell [63]. The cell head gathers the cell data and establish direct communication with the CH. The cells restrict the nodes to communicate with...
The SARS-CoV-2 Spike protein mediates docking of the virus onto cells prior to viral invasion. Several cellular receptors facilitate SARS-CoV-2 Spike docking at the cell surface, of which ACE2 plays a key role in many cell types. The intermediate filamen
prior line of therapy and who are not candidates for autologous stem cell transplant. Outcome measures include overall survival (primary endpoint), progression-free survival, complete response rate, objective response rate, duration of objective response (secondary endpoints), and safety and tolerability...
The bulk of a plant’s biomass, termed secondary cell walls, accumulates in woody xylem tissues and is largely recalcitrant to biochemical degradation and saccharification1. By contrast, primary cell walls, which are chemically distinct, flexible and generally unlignified2, are easier to deconstruct....
