Detailed explanation-1: -Final answer: When the guard cells swell due to the entry of water the stomata get open due to the osmotic potential .

Detailed explanation-2: -To facilitate gas exchange, vascular plants developed microscopic pores called stomata on their outer surface. Stomata are made up of two guard cells that can swell or shrink. Swelling opens the stomata and shrinking closes the stomata.

Detailed explanation-3: -Stomata are pores on the leaf surface, which are formed by a pair of curved, tubular guard cells; an increase in turgor pressure deforms the guard cells, resulting in the opening of the stomata.

Detailed explanation-4: -Guard cells are cells surrounding each stoma. They help to regulate the rate of transpiration by opening and closing the stomata. Light is the main trigger for the opening or closing.

Detailed explanation-5: -A stomatal complex consists of: Guard cells are a pair of kidney-shaped cells that form the opening of the stomate. When the guard cells are turgid (full of water), they are open and allow gas to enter the stomate. However, this also exposes the leaf to potential water loss.
