Through the root hair cells when water enters it passes through the root cortex and the endodermis to reach the xylem the roots have a high wp because they are surrounded by water rich soil the leaves have a low wp which creates a wp gradient which keeps water from flowing from the roots to the . Ib biology- 92 [plant science] outline how the root system provides a large surface area for mineral ion and water uptake by means of branching and root hairs . Ib biology water transport explain how water moves from the soil to the leaves of a plant at first water enters the root by osmosis because the soil water has a lower solute concentration of minerals than the epidermal cell cytoplasm (there is a water potential gradient). Water transport from roots to shoots water potential gradient that causes water to move upwards from the roots through the xylem image credit: openstax biology .

The cohesive and adhesive properties of water molecules allow water transport under tension in xylem and cell walls the roots cells use active transport for the uptake of mineral ions (nitrates) which causes osmosis and the absorption of water.

They are sometimes used interchangeably because the main transport systems included in introductory biology are mass transport systems: in biology, mass flow is the movement of a fluid in one direction , usually through a system of tube-like vessels.

Transport in plants just like humans, plants have a transport system of vessels and cells that transports water, minerals and other nutrients around the plant structure of plants:. Water is a very important transport medium for living organisms because of its solvent properties and because it remains a liquid over a large range of temperatures cohesion the cohesion (stickiness) between water molecules means that a very tall thin column of water can be supported before it breaks. Cohesion, adhesion, and surface tension of water and how they relate to hydrogen bonding.
