Stomata serve a very important function to plants, allowing them to use photosynthesis to make energy for survival. However, water loss, also known as transpiration, occurs when the stomata are open and gases are exchanging, which can be harmful to plants.
Put a fresh leaf in a transparent glass of hot water; the water should be about 60 degrees Celsius.

You should observe some bubbles emerging from the leaf and coming up to the surface of the water.

This emergence of air bubbles demonstrates the presence of pores in the leaf. These pores are called Stomata.

The air inside the leaf will expand when heated, so the extra volume of air is pushed out of the stomata.
