How Does Water Get to the Flower of a Plant?


Plants transport water from the soil surrounding the roots. Plant roots tunnel into the earth to gather water. Many plant root systems have hairlike filaments projecting off them, which increases the surface area of the root system. The more surface area in the roots, the more soil the plant is in contact with and the more water it can draw out of that soil.

Root Pressure

The roots have dissolved minerals or sugars in them. Because the concentration of minerals inside roots is higher than the concentration in the water outside, water enters the roots to try to equalize the concentration in a process called osmosis. This pressurizes the water in the roots, and this root pressure is the main force that helps water get to the flower of a plant.


The water flows out of the roots into the xylem of the plants. Xylem are tubes that plants use to transport water into the leaves and flower petals. The xylem carry not just water, but also dissolved minerals from the soil up the stem of the plant. These minerals will help to nourish the plant and keep it healthy.


Plants feed themselves by a process called photosynthesis, turning water and energy from the sun into sugars which nourish the plants and allow new growth. Plant veins carry water from the stem into the flowers and leaves of the plant. Photosynthesis takes place in the leaves and flowers. Some of the water is used up by the photosynthesis process, and some of it evaporates from the flower petals and leaves, a process called transpiration. During the day, when photosynthesis and transpiration occur, the plant uses up water, and during the night, it rests and replenishes its water and nutrient supplies from the soil.
