In dicot root
1 vascular bundles are scattered and with cambium
2 vascular bundles are arranged in a ring and have cambium
3 xylem and phloem radially arranged
4 xylem is always endarch
Explanation:
(c) The xylem and phloem strands alternate with each other separated by parenchymatous cells. Such kinds of vascular bundles are called radial and found mainly in roots.

Monocot leaves possess
1 intercalary meristem
2 lateral meristem
3 apical meristem
4 mass meristem
Explanation:
(a) Intercalary meristems are derived from apical meristems and separated from the same by permanent cells. They are responsible for localised growth.

What is true about a monocot leaf ?
1 Reticulate venation
2 Absence of bulliform cells from epidermis
3 Mesophyll not differentiated into palisade and spongy tissues
4 Well differentiated mesophyll
Explanation:
(c) In monocot leaves, the mesophyll cells are undifferentiated.
