During the formation of leaves and the elongation of stem, some cells are left behind from the shoot apical meristem and constitute the:
1. Leaf primordium
2. Shoot apical meristematic zone
3. Differentiating vascular tissue
4. Axillary bud

In a dicot root, the number of patches of xylem and phloem are usually:

4. Xylem parenchyma

Monocot root anatomy is different from the anatomy of dicot root in all the following aspects except:
1. More developed pith
2. Polyarch vascular bundles
3. Absence of secondary growth
4. Presence of multicellular root hairs
