Xylem and phloem are present on the same radius, such a vascular bundle is called –

• (a) Radial

• (b) Bicollateral

• (c) Concentric

• (d) Conjoint

When xylem and phloem are arranged in an alternate manner on separate radii, such a vascular bundle is called –

• (a) Radial

• (b) Bicollateral

• (c) Concentric

• (d) Conjoint

Vascular bundle having cambium between the xylem and phloem is called –

• (a) Close vascular bundle

• (b) Open vascular bundle

• (c) Conjoint vascular bundle

• (d) Radial vascular bundle

Vascular bundle without cambium is called –

• (a) Close vascular bundle

• (b) Open vascular bundle

• (c) Conjoint vascular bundle

• (d) Radial vascular bundle

Which one is not the part of stele?

• (a) Pericycle

• (b) Pith

• (c) Vascular bundle

• (d) Cortex

In dicot root, initiation of lateral root, and vascular cambium during secondary growth takes place from –

• (a) Cortex

• (b) Epidermis

• (c) Pericycle

• (d) Xylem

The innermost layer or last layer of cortex is called –

• (a) Pericycle

• (b) Conjunctive tissue

• (c) Endodermis

• (d) Exodermis

I. Unicellular hair

II. Endodermis with passage cells

III. Pith-small / inconspicuous

IV. Radial vascular Bundle

V. Xylem-exarch

VI. 2 - 4 xylem and phloem

The above description refers to which of the following –

• (a) Monocot root

• (b) Dicot root

• (c) Monocot stem

• (d) Dicot stem

Monocot root differs from dicot root in having –

• (a) Polyarch xylem bundles

• (b) Large and well developed pith

• (c) Both

• (d) Radial vascular Bundle and exarch xylem

In root, the tangential as well as radial walls of the barrel-shaped endodermal cells have a deposition of water impermeable, waxy material-suberin in the form of –

• (a) Cuticle strips

• (b) Protein strips

• (c) Casparian strips

• (d) Silicious strips
