Cells of medullary rays that form part of cambial rings | Interfascicular cambium ; c. Loose parenchyma cells rupturing the epidermis and forming a lens-shaped opening in bark | Spongy parenchyma ; d. Large colorless empty cells in the epidermis of grass leaves | Subsidiary cells [/table]
A) In dicot leaves, vascular bundles are surrounded by large thick-walled cells - Conjunctive tissue
B) Cells of medullary rays that form part of cambial rings - Interfascicular cambium
C) Loose parenchyma cells rupturing the epidermis and forming a lens-shaped opening in bark - Spongy parenchyma
D) Large colorless empty cells in the epidermis of grass leaves - Subsidiary cells
Explanation
[Solution] Medullary ray cells that become meristematic and join the cambial ring form interfascicular cambium. The others are bundle sheath, complementary cells (lenticel) and bulliform cells. Answer (2).
