271770 The transverse section of a plant part showed polyarch, radial and exarch xylem, with endodermis and pericycle. The plant part is identified as :

1 Dicot stem
2 Monocot stem
3 Monocot root
4 Dicot root
Anatomy of Flowering Plants

271771 Given below are two statements :
Statement I : Endarch and exarch are the terms often used for describing the position of secondary xylem in the plant body.
Statement II : Exarch condition is the most common feature of the root system.
In the light of the above statements, choose the correct answer from the options given below :

1 Statement I is incorrect but Statement II is true.
2 Both Statement I and Statement II are true.
3 Both Statement I and Statement II are false.
4 Statement I is correct but Statement II is false.
