The correct answer is:
Plants close their stomata during times of intense heat or drought in order to prevent water loss and maintain homeostasis.
Explanation:
Guard cells tend to open stomata within the day when there are lots of day and close stomata at night when the sun is not present and photosynthesis is not happening. They will also close stomata if the air is dry or hot, which minimizes water waste indoors evaporation.
