In which plants do stomata open at night?
This question was addressed to me in an online quiz.
The question is from Organisms and Populations topic in section Organisms and Populations of Biology – Class 12
The correct choice is (d) Succulents
Easy explanation: The stomata open during the night in succulents. These plants show an inverted stomatal rhythm as compared to normal plants. The succulents are usually seen in desert areas. To reduce transpiration these plants secrete waxes or resins.
