Detailed explanation-1: -Stomatal closure at night prevents water from escaping through pores. It maintains the moisture balance according to weather by opening and closing. Stomata facilitate carbon dioxide uptake and release of oxygen during the process of photosynthesis.

Detailed explanation-2: -Plants have little pores (holes or openings) on the underside of their leaves, called stomata. Plants will absorb water through their roots and release water as vapor into the air through these stomata. To survive in drought conditions, plants need to decrease transpiration to limit their water loss.

Detailed explanation-3: -Introduction. Stomata (singular stoma, from the Greek for “mouth”) are pores on the surface of the leaves and other aerial parts of most higher plants that allow uptake of CO2 for photosynthesis and the loss of water vapor from the transpiration stream.

Detailed explanation-4: -stoma (plural stomata) A tiny opening in the surface of a plant leaf or stem. It allows gases and water vapor to escape. Some plants close their stomata at night.

Detailed explanation-5: -This evolutionary innovation is so central to plant identity that nearly all land plants use the same pores-called stomata-to take in carbon dioxide and release oxygen. Stomata are tiny, microscopic and critical for photosynthesis. Thousands of them dot on the surface of the plants.
