Which one of the following choices matches the organs in column I with their vascular system arrangement described in column II? Column I Column II P. Dicot root i. Radial, open, diarch to tetrarch Q. Dicot stem ii. Ring, conjoint, open R. Monocot root iii. Radial, closed, polyarch S. Monocot stem iv. Scattered, conjoint, closed

Options

  1. AP - (ii); Q - (i); R - (iv); S - (iii)
  2. BP - (iii); Q - (iv); R - (i); S - (ii)
  3. CP - (i); Q - (ii); R - (iii); S - (iv)
  4. DP - (iv); Q - (iii); R - (ii); S - (i)

Correct answer

C. P - (i); Q - (ii); R - (iii); S - (iv)

Step-by-step solution

Dicot root (P) has radial vascular bundles with diarch to hexarch (usually tetrarch) xylem. Secondary growth occurs, so it is considered open. Thus, P matches with (i). Dicot stem (Q) has conjoint, collateral, and open vascular bundles arranged in a ring. Thus, Q matches with (ii). Monocot root (R) has radial vascular bundles with polyarch xylem. Secondary growth is absent, so it is closed. Thus, R matches with (iii). Monocot stem (S) has conjoint, collateral, and closed vascular bundles scattered throughout the gr
