Xylem sap of proteoid roots, lateral roots, sinker root and age classes of trunk segments, and phloem sap of mid-trunks were collected from trees of Banksia prionotes (Proteaceae) in native habitat on ...

Journal of Experimental Botany, Vol. 40, No. 219 (October 1989), pp. 1069-1078 (10 pages) The minute changes in volume of a grape berry which occur from hour to hour were measured non-destructively in ...

Transport in biology means carrying substance absorbed or made in the body of an organism to all other parts of its body. In plants, it is only water and minerals that need to be transported to its ...

Asymmetrically transported auxin-efflux carriers cause a polarized flow of auxin, which leads to the formation of continuous columns of procambial cells. In addition, one or more ...

With our sustained high summer temperatures plants need a continuous source of water. Water moves from the soil into and throughout a plant delivering water and nutrients via a pipe-like vascular ...

Plants come in all shapes and sizes, allowing them to fit into unique niches in the landscape, but they can be quite complex organisms. In order to select the most appropriate plants for a given ...

These are distributed differently in roots and stems. In the root, the xylem forms a central column. It forms a solid support. The phloem is towards the centre, outside the xylem. Any green part of a ...

Phloem diseases, including the economically devastating citrus greening, are particularly difficult to study because phloem cells -- essential for plant nutrient transport -- are difficult to access ...

Plants keep growing throughout their lives owing to the activity of stem cells in meristems 1. Genetic analyses have revealed key players such as ligands, receptors and transcription factors involved ...

Meristems are regions of unspecialised cells in plants that are capable of cell division. Meristems make unspecialised cells that have the potential to become any type of specialised cell. They are ...
