Which one of the following statements are correct?

(i) Dicot root always have 2-4 xylem and phloem patches.

(ii) All tissues on the inner side of the endodermis such as pericycle, vascular bundles and pith constitute the stele.

(iii) There are usually less than six years xylem bundles in the monocot root.

(iv) The outer hypodermis consists of few layers of collenchymatous cells just below the epidermis, which provide mechanical strength to the young stem.

(v) The cells of the hypodermis are rich in starch grains and the layer is also referred to as the starch sheath.

(vi) A large number of vascular bundles are arranged in a ring; the ‘ring’ arrangement of vascular bundles is a characteristic of dicot stem.

(vii) The monocot stem has a sclerenchymatous hypodermis and a large number of scattered vascular bundles.

(viii) The adaxial epidermis generally bears more stomata than the abaxial epidermis.

(ix) The sizes of the vascular bundles are dependent on the size of the veins.

(x) In grasses, certain adaxial epidermal cells along the veins modify themselves into large, empty, coloured cells. There are called buliform cells.

(xi) In dicot stems, the cells of cambium present between primary xylem and primary phloem is the intrafascicular cambium.

(xii) The cells of medullary rays adjoining interfascicular cambium become meristematic and form the intrafascicular cambium.
