These are known as stomata - pronounced stoh-muh-tuh ; the singular form is stoma.
The are generally found on the underside of the leaves and sometimes along the stems; theyallow for gaseous exchange between the leaf and the atmosphere. Carbon dioxide in and water vapour and oxygen out (transpiration).
They are normally on the underside of leaves as the waxy cuticle covers the upper epidermis; strangely some plants that are grown in tissue culture have stomata on both leaf surfaces, as a cuticle does not develop until the tissue culture plantlets are exposed to an open environment (and ultraviolet light).
Plants growing in arid areas have fewer stomata to reduce transpiration where as plants in tropical areas have large or many stomata to take advanatge of the ideal growing conditions.

What are the pores tiny leaves have called?
Leaves have small openings called stomata on the underside of the blade. Stomata function in gas exchange.
What are the tiny holes in plant's leaves called?
Stoma (plural stomata), they are the pores used for gas exchange.
Which part of the leaves need carbon dioxide?
stoma
How does oxygen exit a leaf?
Oxygen leaves the leaf because it is actually useless to the plant. We breathe in oxygen, because we need it to survive, and we breathe out carbon monoxide, which is contained in our cells but is harmful to us. Plants work together with us - as we breathe out the carbon monoxide, they take it in because they need it, and in return they let out oxygen, which we need.

Where most of the water leaves the leaf?
Water leaves the leaves of a plant through pores they have that opne and close. This process is called transpiration.
What are small openings on the underside of a leaf called?
They are called stomata, openings or pores in the epidermis of leaves.
How do leaves releas water?
through small pores called stomata by the process of transpiration.
Tiny pores called stomata on the bottom of the leaves take in what from the air?
The stomata are on the bottom of the leaves to aid in respiration. The pores allow carbon dioxide to enter the leaf. This allows for the continuation of photosynthesis by plants. They have a very important role in photosynthesis.
What are tiny holes in plants leaves called?
Stoma (plural stomata), they are the pores used for gas exchange.
Where does CO2 enter plants?
co2 entres through small pores called stomata present on leaves of plants.
Are flowers able to breathe?
yes, flowers breathe through tiny holes in there leaves and stems called pores
What is the tiny holes in leaves through which air passes?
The pores used for plant respiration are called stomata.
How does carbon dioxide get in to the leaves so photosynthesis can occur?
There are tiny pores on the leaf called stomata which allow gases in and out.
