Ascent of sap

Index Ascent of sap

The ascent of sap in the xylem tissue of plants is the upward movement of water and minerals from the root to the crown. [1]

8 relations: Disjoining pressure, Jagadish Chandra Bose, Lignin, Root, Transpiration, Van der Waals force, Vital theory, Xylem.

Disjoining pressure

Disjoining pressure (symbol Πd), in surface chemistry, according to an IUPAC definition, arises from an attractive interaction between two surfaces.

Jagadish Chandra Bose

Sir Jagadish Chandra Bose, CSI, CIE, FRS (30 November 1858 – 23 November 1937), also spelled Jagdish and Jagadis, was a polymath, physicist, biologist, biophysicist, botanist and archaeologist, and an early writer of science fiction.

Lignin

Lignin is a class of complex organic polymers that form important structural materials in the support tissues of vascular plants and some algae. Lignins are particularly important in the formation of cell walls, especially in wood and bark, because they lend rigidity and do not rot easily. Chemically, lignins are cross-linked phenolic polymers.

Root

In vascular plants, the root is the organ of a plant that typically lies below the surface of the soil.

Transpiration

Transpiration is the process of water movement through a plant and its evaporation from aerial parts, such as leaves, stems and flowers.

Van der Waals force

In molecular physics, the van der Waals forces, named after Dutch scientist Johannes Diderik van der Waals, are distance-dependent interactions between atoms or molecules.

Vital theory

"Vital force theory" is a proposed mechanism for the ascent of sap through the xylem tissue of plants.

Xylem

Xylem is one of the two types of transport tissue in vascular plants, phloem being the other.
