the differences between Vessel Tube and Sieve Tube.
Difference # Vessel Tube:
1. It is a long distance channel for water transport.
2. A vessel is made up of a large number of dead cells.
3. The wall is thick.
4. The wall possesses pits and other types of secondary thickenings.
5. The wall is lignified.
6. The end walls between adjacent cells are completely dissolved.
7. The region of end walls is not swollen or conspicuous.
8. In addition to transport, a vessel also helps in providing mechanical strength.
Difference # Sieve Tube:
1. Sieve tube is a long distance channel for transport of organic nutrients.
2. It is made up of number of living cells.
3. The wall is thin.
4. Secondary thickenings are absent. Plasmodesmata occur instead.
5. Lignification is absent.
6. The end walls are perforated with pores called sieve pits.
7. The end walls are generally broader than the rest of the sieve tube elements.
8. A sieve tube does not provide mechanical strength. Hope it helps you...
