Question

Lateral roots arise from primordia developed by division of

• A. Pericycle cells in between two protoxylem points
• B. Pericycle cells opposite protoxylem points
• C. Endodermis cells in between two protoxylem points
• D. Endodermis opposite protoxylem points

Answer 1

The correct option is A Pericycle cells in between two protoxylem points

Lateral roots arise endogenously from other roots and increase the absorptive surface of the plant. Most lateral roots are initiated some distance basipetal to the apical meristem, differentiated cells must become reprogrammed to give rise to the initial divide and enlarge in very precise patterns to organize a new organ recognizable as a root.
