What substance/substances are transported in plants by : (a) xylem vessels and tracheids ? (b) sieve tubes (or phloem) ?
One of the main difference between xylem and phloem is that xylem can conduct substances only in one direction, whereas, phloem can transport substances in both directions.
The transport of water through xylem and transport of organic substances through phloem are achieved respectively by
