An old piece of dicot stem and a dicot root is given to a candidate during practical examination. Which of the following anatomical structures can be used to distinguish between the two?
MEDIUM

The transverse section of a plant shows following anatomical features:

(a) Large number of scattered vascular bundles surrounded by bundle sheath
(b) Large conspicuous parenchymatous ground tissue
(c) Vascular bundles conjoint and closed
(d) Phloem parenchyma absent

Identify the category of plant and its part:

EASY

Assertion (A): The veins vary in thickness in dicot leaves, with reticular venation.

Reason (R): The size of the vascular bundles is dependent on the size of the veins.

MEDIUM

Read the following statements about the vascular bundles:
(a) In roots, xylem and phloem in a vascular bundle are arranged in an alternate manner along the different radii.
(b) Conjoint closed vascular bundles do not possess cambium.
(c) In open vascular bundles, cambium is present in between xylem and phloem.
(d) The vascular bundles of dicotyledonous stem possess endarch protoxylem.
(e) In monocotyledonous root, usually there are more than six xylem bundles present.
