A plant with high turgor is healthy and rigid.

The water pressure inside the plant cell is called as turgor pressure, which is maintained by the process of osmosis in which the water moves across a permeable membrane from a place of higher concentration to lower concentration. The turgor pressure makes the plant cell in the swollen state and it exerts the pressure against the neighboring cells, these neighboring cells also maintains the same turgidity. This provides the rigidity to the plant structure, hence prevents wilting of the plant.

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.
