In the following diagram of the stomatal apparatus, which parts are correctly labelled ?

• A. (i) and (v)
• B. (ii) and (v)
• C. (iv) and (ii)
• D. (v) and (iv)

Answer 1

The correct option is A (i) and (v)

i) Guard cell
ii) Guard cells have a thick inner wall, so it is labelled wrongly.
iii) the outer wall of the guard cell. So it is also labelled wrong.
iv) epidermal cell.
From the question figure, it is clear that only guard cells and Epidermal cells are correctly labelled. So, the correct answer is option A.
