All plant cells are capable of taking up water. Even dead ones do to a certain degree. Absorption of water by dead cell walls makes wood become larger. In common land plants, the living cells of roots take up most of the water. Land plants without roots do exist, however. Those greeni...

Topoisomerase activity is indispensible to cells, but requires the transient breakage of DNA strands. This property has been exploited, often for significant clinical benefit, by various exogenous agents that interfere with cell proliferation. Despite decades of study, surprising findings involving ...

aIn plant cells, pectin consists of a complex set of polysaccharides that are present in most primary cell walls and particularly abundant in the non-woody parts of nearly all terrestrial plants. 在植物细胞,果胶包括在几乎所有地球植物的non-woody部分上是存在多数主要细胞壁和特别丰富的复杂套多聚糖。
ImageJ was utilized to quantify the areas of red and green fluorescence, which produced average values. These numerical values were subsequently used in the quantification formula to determine the fluorescence intensity of live/dead cells in equation (4):...
