    C. Lenticels
  3. Accessory cells
    D. Subsidiary cell
  4. Isobilateral leaf

A - 3, B - 1, C - 2, D - 4

A - 1, B - 2, C - 3, D - 4

A - 4, B - 3, C - 2, D - 1

A - 4, B - 1, C - 2, D - 3

Solution:

Bulliform cells are the large, bubble-shaped epidermal cells that are present in groups on the upper surface of the isobilateral leaves in monocots (A-4).Each stomatal pore is surrounded by two guard cells that assist in the stomatal opening (B-1).Lenticels are the aerating pores formed by rupture of the epidermis of root and stem at several places after secondary growth (C-2).The epidermal cells that border the guard cells are called subsidiary cells (D-3).
