Detailed explanation-1: -A stoma is an opening on the abdomen that can be connected to either your digestive or urinary system to allow waste (urine or faeces) to be diverted out of your body. It looks like a small, pinkish, circular piece of flesh that is sewn to your body.

Detailed explanation-2: -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-3: -The epidermis aids in the regulation of gas exchange. It contains stomata, which are openings through which the exchange of gases takes place.

Detailed explanation-4: -Stomata resemble doughnuts-a circular pore with a hole in the middle for gas to enter or leave the plant. The pore consists of two cells-each known as a guard cell.
