During secondary growth in dicot root some part of vascular cambium originates from the tissue
located _______ the phloem and a portion of pericycle tissue ______ the protoxylem.
(1) Above, below
(2) Below, above
(3) Below, below
(4) Above, above
During secondary growth in dicot root, the vascular cambium is completely secondary. It originates from the tissue located just below the phloem, and a portion of pericycle tissue above the protoxylem, forming a complete ring. Thus, the correct answer is (2) below, above
