Identify the labels 'X' and 'Y' in following figure.

Options

  1. AX - Epidermal cell, Y - Guard cell
  2. BX - Guard cell, Y - Epidermal cell
  3. CX - Subsidiary cell, Y - Guard cell
  4. DX - Guard cell, Y - Subsidiary cell

Correct answer

D. X - Guard cell, Y - Subsidiary cell

Step-by-step solution

The given figure illustrates the structure of a stomatal apparatus. Label 'X' points to one of the two bean-shaped cells that enclose the stomatal pore. These are the guard cells, which contain chloroplasts and are responsible for regulating the opening and closing of the stoma.
