Stomata:

  • These are the tiny openings or pores in the epidermal system of plants, especially  leaves.
  • Stomata can also occur in stem. 
  • The stomata are surrounded by specialised epidermal cells called guard cells that regulate the opening and closing of stomata.
  • Guard cells are generally bean-shaped in dicots and dumbbell shaped in monocots.
  • Stomata regulate the gaseous exchange and transpiration. 
  • Some surrounding epidermal cells become specialised to form the subsidiary cells. 
  • The stomatal aperture, guard cells and subsidiary cells are called stomatal aperture.
