• A. Part (B) mainly helps in absorption of water
• B. Quiescent centre is present in part (B)
• C. Part (A) is most suitable for anatomical studies of root.
• D. Differentiation of cells can be observed in part (C)

Answer 1

Answer: (C)

Part (A) is the root hair zone which represents the zone of differentiation or maturation. This is the most suitable part for anatomical studies of root because different types of primary tissues differentiate or mature in this region. Xylem, phloem, pericycle, endodermis, cortex and epiblema are clearly visible in this region.
