In an experiment, a student cut a transverse section of young stem of a plant which he has taken from his school garden. After observing it under the microscope how would he ascertain whether it is a monocot stem or a dicot stem?
1 With the help of bulliform cells.
2 With the help of casparian strips.
3 With the help of vascular bundles.
4 With the help of stomatal apparatus.
Explanation:
(c) By observing the arrangements of vascular bundles, the student will discover the nature of stem. If the vascular bundles are arranged in a ring then it is a dicot stem and if the vascular bundles are scattered, then it is a monocot stem.

In stems, the protoxylem lies towards the and the metaxylem lies towards the of the organ.
1 centre; periphery
2 periphery; centre
3 periphery; periphery
4 centre; centre
Explanation:
(a) The first formed primary xylem elements are called protoxylem and the later formed primary xylem is called metaxylem. In stems, the protoxylem lies towards the centre (pith) and the metaxylem lies towards the periphery of the organ. This type of primary of the organ. This type of primary xylem is called endarch.
