They are called stomata, tiny holes that regulate the intake/output of gas, such as carbon dioxide and oxygen.
Surface tension.
The ozone hole allows some radiations to reach the earth's surface. These radiations are high energy UV radiations.
it lets to the ultra violet rays reaching the earth surface causing greenhouse effect and global warming
The openings on the underside of leaves which allow CO2 (Carbon Dioxide) to enter the plant are known as (singular ). They also allow O2 (oxygen) to exit the plant.
Volcanoes
microscopic openings on the surface of leaves that allow gas to pass in and out
They are called stomata, tiny holes that regulate the intake/output of gas, such as carbon dioxide and oxygen.
The openings where gases enter and leave plant leaves are called stomata's. These are crucial for the survival of plants.
It's called a stoma (plural stomata) and its function is to allow carbon dioxide to enter the leaf for photosynthesis. The guard cells sre responsible for regulating the size of the stoma.
No in fact they have multiple openings called pores, which allow water and nutrients to flow in and out of the sponge
stomata
They are called spiracles, tiny tubes alongside the insect's body which allow it to receive air. Kind of like gills, but for insects. Good luck!

According to : www.wikipedia.org/wiki/spiracles"Spiracles are small openings on the surface of some animals that usually lead to respiratory systems."In fish, such as sharks & rays these openings are used to allow the animal to 'rest'. They pump air across the gills when the animal is still.
The function of stomata is that they are small openings or pores on the surface of leaves.The function of stomata is to allow gases such as oxygen, water vapor, and carbon dioxide to move around the leaf.
