植物一生都在生长; 这被称为不确定生长,它将植物与大多数动物区分开来。 尽管植物的某些部分停止生长(例如,叶子和花朵),但其它部分却不断生长-像根和茎。 植物中不确定的生长是由含有未分化细胞的组织(称为分生组织细胞)启用的。当分生细胞分裂时,一些子细胞留在分生组织中,确保未分化细胞的稳定供应。其它子细胞拉...

Growth in plants occurs as the stems and roots lengthen. Some plants, especially those that are woody, also increase in thickness during their life span. The increase in length of the shoot and the root is referred to asprimary growth, and is the result of cell division in the shoot apica...

In plants, Graminaceae species employ plant specific siderophores while non-Graminaceae such as Arabidopsis thaliana depend on an iron reduction-based uptake strategy2. During pathogen attack, iron is at the nexus of host–pathogen interaction as both organisms compete for this metal. Pathogens ...

In plants, growth occurs in meristems, which are the site of repeated cell division of unspecialized cells. These cells differentiate and become specialized in relation to the function they will perform. Learn more about plant meristems in this tutorial.
In a biology experiment on the influence of different fertilizers on plant growth, when recording the growth data, we should ___. A. record only the height of the plants B. record the data once a month without looking at the plant condition C. record various data such as height, leaf ...
Plants in nature are continuously exposed to several biotic and environmental limitations. Among these limitations, soil water deficit is one of the most adverse factors of plant growth and productivity and is considered a severe threat for sustainable crop production in the conditions of changing clim...
