Epidermal Tissue · Botany

Which adaptation of sunken stomata helps plants survive in dry habitats?

  1. They significantly increase the direct exposure of stomata to prevailing wind
  2. They reduce air movement around stomata and lower water loss
  3. They prevent carbon dioxide from entering leaves
  4. They replace the need for xylem tissue
Show answer and explanation

Correct answer: They reduce air movement around stomata and lower water loss

Sunken stomata are located below the leaf surface, often in pits. This creates a humid microenvironment and reduces water loss by limiting air movement around the stomatal pores.
