The transverse section of plant part showed polyarch, radial and exarch xylem, with endodermis and pericycle. The plant part is identified as:
Read the following statements about the vascular bundles: [NEET 2022 Phase 1] (a) In roots, the 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 the monocotyledonous root, usually there are more than six xylem bundles present. Choose the correct answer from the options given below:
Plants having little or no secondary growth are: (NEET 2018)
Answer & NCERT explanation
Correct answer: C — C, E, A, D, B
In monocot root from periphery to center: Epidermis (outermost), Cortex (storage tissue), Endodermis (with Casparian strips), Pericycle (gives rise to lateral roots), Pith (central ground tissue). This is the standard anatomical arrangement described in NCERT Chapter 6.

The anatomy of the monocot root is similar to the dicot root in many respects. It has epidermis, cortex, endodermis, pericycle, vascular bundles and pith. As compared to the dicot root which have fewer xylem bundles, there are usually more than six (polyarch) xylem bundles in the monocot root. Pith is large and well developed. Monocotyledonous roots do not undergo any secondary growth.
NTA tests your knowledge of monocot root anatomy and how it differs from dicot roots. Students often confuse the number of xylem bundles: dicots have 2-4 (diarch to tetrarch), while monocots have MORE THAN 6 (polyarch). Another common mistake is assuming monocots undergo secondary growth like dicots do—they don't. Remember the tissue sequence from outside to inside: epidermis → cortex → endodermis → pericycle → vascular bundles → pith. The large, well-developed pith and multiple xylem bundles are key distinguishing features. NEET frequently asks you to identify root type from anatomical diagrams or to compare dicot-monocot differences, making this high-yield.
