19 lip 2008 · The document summarizes the key components and functions of xylem and phloem tissue in plants. Xylem tissue conducts water and minerals throughout the plant and is composed of tracheids and vessels. Phloem tissue conducts sugars and transports them from leaves to other plant parts.
2 wrz 2011 · Xylem contains tracheids and vessels which are dead cells with lignified walls that transport water and minerals throughout the plant. Tracheids are elongated cells with thickened walls, while vessels are formed from rows of cells with dissolved walls to form continuous channels.
The document describes the structure and function of xylem and phloem in vascular plants. It explains that xylem consists of tracheids, vessels, and parenchyma cells that transport water and minerals upward from the roots, while phloem contains sieve tubes and companion cells that transport sugar downward from leaves.
