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)

'M' is the endodermis, which is the innermost layer of cortex and usually lacks Casparian strips in a dicot stem. 'N' is the sclerenchymatous 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.
