Question

Q2) Explain why it is useful for stomata to open during daylight, and to close at night?

Answer 1

Answer:

A plant's stomata are easy to see -- paint the underside of the leaf with clear nail polish, peel it off when dried and examine the clear leaf print under a microscope. But as fascinating as these stomata look, their function is even more exciting. Responsible for the plant's carbon dioxide and water regulation, stomata are often closed at night and reopen with the sunrise, an adaptation that is key to these plants' survival.
