    Lateral root or ginates from :

    A)  endodermis    

    B)  pericycle

    C)  cortex         

    D)  phloem

    Correct Answer: B

    Solution :

    The lateral roots arises from the cells of pericycle and hence the root branches are said to be endogenous in origin (arising from inner layer of endodermis). Cortex is situated below the epibiema and is made up of thin walled circular or- polygonal cells with intercellular spaces. Cortical cell? store starch. The innermost layer of cortex the surrounds the stele is called endodermis. Cells of endodermis have special thickenings called Casparian Strips. Phloem is complex tissue of root and conduct the food from leaves through stem to root.
