| 释义 | turgor noun[ U ] biology specializeduk /ˈtɜːɡər/ us /ˈtɝːɡɚ/ the normal state of how hard a cell is, caused by its contents pressing against the cell wall（细胞）胀满 Cells actin anaphase anti-platelet assort axoplasm histochemistry histography homologous chromosomes infiltration intercellular neoplasia nerve fibre neurofibril neurofibrillary neuroglia teratoma tetrad thrombocyte thymocyte unciliated Examples of turgorturgor It is intriguing how the turgor in the single-cell fibre is maintained and regulated. Increases in embryo osmotic potential and in the turgor yield thresholds of both the radicle and the endosperm/pericarp envelope contributed to this change. This, together with increases in tissue elasticity, had reduced the leaf water potential at which turgor loss occurred. Affected cells are characterized by loss of turgor and lack of distinguishable organelles. The loosening reduces the turgor pressure and establishes a water potential gradient across the cell membrane. Asterisk: space between plasma membrane and cell wall due to turgor loss. Reduction of embryo expansion by turgor limitation is one of the most direct. The transgenic seedlings were only marginally affected over the 7-h air-drying period and after rehydration, they fully recovered turgor and recommenced growth. The dead epidermal cells lack turgor and have heavily folded walls. Measures of water content and water and turgor potentials did not reveal signs of a mild water stress in either treatment. Available water is required to ensure the positive turgor pressures necessary to expand growing cells during leaf flush, flowering and fruit development. Increasing turgor in the growing perivitelline space may even squeeze out the tips of the microvilli over the surface of the vitelline envelope. Figure 9c shows an example of mostly intact axis cells covered with a layer of damaged endosperm cells that are characterized by loss of turgor and lack of distinguishable organelles. Egg jelly precursor molecules thus seem to penetrate the vitelline envelope, but slowly and after swelling and turgor pressure has set in. Ester loading proves to be unsuccessful in most cases and the cell wall and turgor make plant cells difficult to microinject. These examples are from corpora and from sources on the web.
