-How plants get liquid and minerals- Flowers absorb liquid through their roots‚ which are attached to xylem vessels. Xylem vessels are tubes that can expand through several feet of tissue and be .7mm in diameter. Their walls are thickened with cellulose deposits. Xylem bring water up to the leaves and petals of the plant. Even without contact with the roots‚ the xylem can still absorb water. Because of this‚ a cut flower usually doesn’t die for a couple days (as long as it is placed in water of
