Xylem and Phloem
These are the two types of vascular tissue in plants, and they are responsible for the transport of water, nutrients, and organic compounds.
-
Xylem: Transports water and dissolved minerals from the roots to the rest of the plant. It also provides mechanical support. Composed of tracheids and vessel elements in angiosperms, and tracheids in gymnosperms.
-
Phloem: Transports organic nutrients, particularly sucrose, from the leaves to the rest of the plant. Consists of sieve tube elements and companion cells.
Each of these components plays a vital role in the growth, development, and functioning of plants and animals.
