The correct answer is option 3: Subsidiary cells. Subsidiary cells are specialized cells that are closely associated and interact with guard cells in plant leaves. The subsidiary cells are found on either side of the guard cells in the leaf epidermis. They play a crucial role in regulating the opening and closing of stomata, which are small openings on the leaf surface through which gases and water vapor are exchanged. The subsidiary cells help in the movement of water, ions, and photosynthates between the guard cells and the surrounding tissues. They provide support and assist in maintaining the turgor pressure of the guard cells, influencing the control of stomatal movement. Subsidiary cells are an important component of the stomatal complex and are essential for the proper functioning of stomata and overall plant physiology.
