Vegetal structure

The places from which pollutants emanate are called sources. There are natural as well as anthropogenic sources of the permanent gases considered to be pollutants. These include plant and animal respiration and the decay of what was once living matter. Volcanoes and naturally caused forest fires are other natural sources. The places to which pollutants disappear from the air are called sinks. Sinks include the soil, vegetation, structures, and water bodies, particularly the oceans. The mechanisms whereby pollutants...

The extraction of vegetable plant-material requires careful selection of raw materials, in connection with chemical analysis, because the content of the vegetables to be extracted can vary substantially. Also the possibility of high concentrations of undesired substances - either contained within them, or contaminations such as pesticides - can influence the product quality enormously. Exhaustive extraction is not always possible with acceptable effort, owing to the vegetable structure, and the extraction efficiency using low-quality raw materials may be too poor to allow economic processing.

Other belowground vegetative structures (i.e., roots and seed tuber) have only a relatively small proportion of the total carbon, though the root contribution is typically underestimated due to incomplete recovery during excavation. Thus, aboveground plant parts, in particular stems/branches,...

In soil, mycorrhiza produces vegetative structures like chlamydospores and zygospores, which become dominant during the period of environmental stress and germinate with the return of favourable conditions (Bhoon, 2005 Kumari et al, 2003). Thus, they are better equipped for combating the unfavorable conditions and have larger shelf lives as compared to bacterial systems.

The diversity of form shown by fruit and vegetable structures is extremely wide. Among the vegetables there are representatives of all the recognizable morphological divisions of the plant body — whole shoots, roots, stems, leaves, and fruits.
