Answer 1

Answer: (A)

Bulliform cells are specialized, thin walled epidermal cells, frequently occurring in members of family Graminae. Guard cells are kidney shaped (in dicots) or dumb-bell shaped (in monocots) chloroplast containing cells, found in the stomata. Lenticels are aerating pores, adopted for exchange of gases and frequently found in secondory cortex. Subsidiary cells are simple, thin walled cells, generally occurring associated with stomata .
