Select the correct pair:

  1. A
    Cells of medullary rays that form part of cambial ring - Interfascicular cambium
  2. B
    Loose parenchyma cells rupturing the epidermis and forming a lens-shaped opening in bark - Spongy parenchyma
  3. C
    Large colorless empty cells in the epidermis of grass leaves – Subsidiary cells
  4. D
    In dicot leaves, vascular bundles are surrounded by large thick-walled cells – Conjunctive tissue

Solution & Step-by-step Explanation

1. Correct pair: Cells of medullary rays adjoining the intrafascicular cambium become meristematic and form the interfascicular cambium.2. Lens-shaped openings are Lenticels (formed by phellogen).3. Large empty cells in grasses are Bulliform cells.4. Cells surrounding vascular bundles in leaves are Bundle sheath cells.
