WebMay 9, 2024 · Both of these predictions – stomatal closure and stomatal opening – are in fact correct: following an increase in water loss or a decrease in water supply, stomata transiently ‘pop open’ before eventually closing (e.g. Fig. 3). The transient opening is called the ‘wrong-way response’ (WWR) and the subsequent steady-state closure is ... WebCorrect option is A) Transpiration is loss of water from aerial parts through stomata. Opening of stomatal pore is regulated by guard cells. When guard cells gain water, they become turgid. In turgid guard cells the thin outer wall is pushed outside, which pulls the thick inner wall outside. This causes opening of stomata.
