(ii) Sayre (1926) observed that stomata open in neutral or alkaline pH, which prevails during day time due to constant removal of carbon-dioxide by photosynthesis. asked Apr 14, 2015 by shiv (2,208 points) Tags. Stomata occur on both upper and lower surfaces of leaf, but especially they are confined to the lower surface. The change in turgor, or hydrostatic pressure, within a guard cell pair is the result of the osmotic water flow across the cell walls. Stomata remain closed during night when there is no photosynthesis and due to accumulation of carbon-dioxide, carbonic acid is formed that causes the pH to be acidic.
