Question

what is the difference between Tracheids and sieve tubes?

Answer 1

The difference between tracheids and vessels is that vessels have perforations at the end plates which make them a tube-like, long structure while tracheids do not have end plates.

Answer 2

These cells are devoid of protoplast when mature. These non-living cells are elongated with lignified cell walls. The main difference between tracheids and vessels is that vessels have perforations at the end plates which make them a tube-like, long structure while tracheids do not have end plates
