The upcoming discussion will update you about the differences between Tracheid and Fibre.
Difference # Tracheid:
1. It is a tracheary element.
2. Tracheid is found only inside xylem.
3. It is 1-6 mm in length.
4. Cell wall is comparatively less thickened.
5. The lumen is wide.
6. Thickening can be annular, spiral, reticulate, scalariform and pitted.
7. Pits are generally bordered.
Difference # Fibre:
1. It is a mechanical element.
2. Fibre occurs inside xylem, phloem, around vascular bundle, inside peri-cycle, cortex, hypodermis, etc.
3. A fibre can be 1 mm to 90 cm in length.
4. Cell wall is comparatively more thickened.
5. The lumen is narrow.
6. Fibre has pitted thickening.
7. Pits are usually simple.
