Expert Answer:

  • The opening and closing of stomata depends upon the turgidity of the stomata.  
  • When guard cells become turgid, stomata open and while guard cells become flaccid stomata close.
  • Guard cells contain chloroplast hence they synthesize food by photosynthesis, using carbon dioxide during day time.
  • Thus, due to lack of carbon dioxide, ​the pH value of the cell increases (7.5 pH).
