Vedclass · Answer

(C) In plants of the family $Fabaceae$ (Leguminosae), the formation of root nodules is a complex process involving the interaction between the host plant and nitrogen-fixing bacteria like $Rhizobium$.When the bacteria come in contact with the root hairs, they induce the root hair to curl.The bacteria then enter the root hair and travel through an infection thread.This infection thread reaches the inner layers of the root, specifically the $Cortex$ and $Pericycle$ cells.The bacteria stimulate the cortical cells to divide rapidly, leading to the formation of the root nodule structure.

Which plant tissue of the root is responsible for the formation of root nodules in plants of the family $Fabaceae$?
