Solution

  vascular bundles
of dicot
vascular bundles of monocot
1. Diarch, triarch or tetrarch condition can be observed. (Xylem bundles vary from two to six number) Polyarch condition is observed. (xylem bundles are more than six)
2. Cambium is formed in later stage between xylem and phloem which causes secondary growth. Secondary growth is absent.
3. Vascular bundles are arranged in the form of a ring. Vascular bundles are scattered in the ground tissue.
4. It is conjoint, collateral and open (Cambium present) They are conjoint, collateral and closed (cambium is absent).
5. Vascular bundle is not surrounded by a sclerenchymatous bundle sheath. Vascular bundle is surrounded by a sclerenchymatous bundle sheath.
6.  Vascular bundles of varying size. The size of the vascular bundles is dependent on the size of the veins which vary in thickness in dicot leaf. Vascular bundles are nearly of similar size (Except in main veins).
