Apart from what's written in the article, stomata typically close at night as there's no sunlight so no photosynthesis. When osmotic pressure of guard cells increases, water enters into it and makes stomata open. The size of the stomatal opening is used by the plant to control the rate of transpiration and therefore limit the levels of water loss from the leaf. So, for CO2 to get in for the plant to photosynthesize food, water gets out. They also have radial fibers all around. Apart from water vapour loss in transpiration, exchange of oxygen and carbon dioxide in the leaf also occurs through these stomata. This depends on the photosynthesis type of the plant: C3, C4 or CAM. Only the fool needs an order the genius dominates over chaos. Once the water is lost, the guard cells become flaccid and the stomata closes. This is the opposite of opening since it takes place when the water inside the guard cells is eliminated, causing them to become flaccid. When the water gets into the cell, the radial fibers tend to push the cell wall out and the hence the cell curves leading to the opening of the stomata.
