ADVERTISEMENTS:
The upcoming discussion will update you about the differences between Dicot Root and Monocot Root.
Difference # Dicot Root:
1. Cortex is comparatively narrow.
2. The epiblema, the cortex and even the endodermis are peeled off and replaced by cork.
ADVERTISEMENTS:
3. Older root has a covering of cork.
4. Endodermis is less thickened and casparian strips are more prominent.
5. Passage cells are generally absent in endodermis.
6. Pericycle produces lateral roots, cork cambium and part of the vascular cambium.
ADVERTISEMENTS:
7. The number of xylem and phloem bundles varies from 2-5 or sometimes 8.
8. Xylem vessels are generally angular.
9. Conjunctive tissue is parenchymatous.
ADVERTISEMENTS:
10. Conjunctive parenchyma forms the cambium.
11. Secondary growth takes place with the help of vascular cambium and cork cambium.
12. Pith is either absent or very small.
Difference # Monocot Root:
1. Cortex is very wide.
2. Cork is not formed. The cortex and the endodermis persist. Only the epiblema is peeled off.
ADVERTISEMENTS:
3. Older root has a covering of exodermis.
4. Casparian strips are visible only in young root. The endodermal cells later become highly thickened.
5. Thin walled passage cells generally occur in the endodermis opposite the protoxylem point.
6. Pericycle produces lateral roots only.
ADVERTISEMENTS:
7. Xylem and phloem bundles are numerous and are 8 or more in number.
8. Xylem vessels are oval or rounded.
9. Conjunctive tissue may be parenchymatous or sclerenchymatous.
7. Conjunctive parenchyma does not produce cambium.
ADVERTISEMENTS:
10. Secondary growth is absent.
11. A well-developed pith is present in the center of the root.
