Question

Consider the following statements regarding the given figure and select the correct one.

• A. $L$' is the collenchymatous hypodermis that provides mechanical strength and flexibility to young dicot stems
• B. $M$' is the innermost layer of cortex which usually possesses Casparian strips
• C. $N$' is the parenchymatous pericycle that synthesises food
• D. $O$' is xylem which is exarch with respect to the positions of protoxylem and metaxylem

Answer 1

Answer: (A)

$L$' is the collenchymatous hypodermis that provides mechanical strength and flexibility to young dicot stems

Answer 2

$M$' is the endodermis, which is the innermost layer of cortex and usually lacks Casparian strips in a dicot stem. '$N$' is the sderenchymatous pericyde that provides mechanical strength. '$O$' is xylem which is endarch (centrifugal) i.e., protoxylem (first formed xylem) lies towards the pith or centre of the stem.
