Anatomy of a tea plant茶树的生理结构根 root system茶树根系由主根、侧根和须根组成。主、侧根用来固定茶树，须根又称吸收根，用来吸取水分和营养，再由主、侧根输送到地上部分。茶树的主根可垂直深入土层2米至3米，地下深度远大于地上高度，是名副其实的“根深叶茂”。例句：1、The root system of a tea pl...
BACKGROUND AND AIMS: In spite of the importance of Retama species for dune stabilization and re-vegetation and the contribution to the bio-fertilization of semi-arid and arid ecosystems, the symbiotic interaction of Retama species with rhizobia remains largely unstudied. In this paper, we aim to...
These proceedings contain 7 papers covering the following topics: root cortex development and structure; cell ultrastructure in root aerenchyma; metal uptake; the impact of rhizospheric processes on porewater; xylem sap flow and shoot hydraulic resistance; root aeration and species distribution; and oxy...
of the aortic root as a whole: the intermittent, unidirectional channeling of large volumes of fluid, while maintaining laminar flow, minimal resistance and least possible tissue stress and damage, during varying haemodynamic conditions and demands (2-4). This well-coordinated dynamic behavior of ...

Roots of Voyria truncata retain the primary root structure even though they can grow as thick as 2 mm in diameter. These root diameters are due to a retained capability for cell division in the cortex parenchyma. This is explained as a vital adaptation to its life form. Based on the extra...
