Most plants absorb water from a wide area of soil using osmosis in their roots. Some plants (a few species of epiphytes) have specialized surface cells that let them absorb water from the air.
unlike evaporation which is part of the water cycle; plants draw water from below the evaporation zone; water that is tightly held by clay particles is drawn up by the plants in the transpiration stream and diffused into the atmosphere.
Adhesion and cohesion properties of water allow plants to draw liquid up from their roots through capillary action. Water molecules stick to each other (cohesion) and to the walls of the plant's vascular system (adhesion), creating a continuous column of water that can be pulled up through the plant by transpiration (loss of water through leaves).
Osmosis
hydrogen bonding of the water and water potential gradient between the soil and the roots. the process is driven by transpiration of plants
Carnations, daisies, and white roses are popular choices for changing color with food coloring because they have a high water uptake capacity. Placing the flowers in water mixed with food coloring allows the petals to absorb the color and change over time.
Bryophytes are a type of non-vascular plants that draw up water by using osmosis. One of the more well known plants within this group are species of moss.

too much salt in the water inhibits the plants ability to draw water from the soil and eventually it will die of thirst

Cohesion is the attraction between water molecules that allows them to stick together. In plants, this cohesion helps water molecules move up from the roots to the leaves through a process called capillary action. As water evaporates from the leaves, it creates a pull that helps draw more water up through the plant's vascular system. This cohesive force is essential for the efficient transport of water in plants.
Plants use capillarity to draw water from the soil into their roots. As water evaporates from the leaves, it creates a tension that pulls up more water from the roots through capillary action.
