A stomata is found all the way around a leaf, they are small openings so carbon dioxide can get in to the leaf and nurish it. :)
Natural ones are called orifices. Artificial ones are called stomas.
The Celebration Belt will fit either right side or left side stomas and is an excellent choice for ostomates with colostomy, ileostomy and urostomy procedures

Many plants, called C3 and C4 plants, open their stomas during the day to let in carbon dioxide to instigate the process of cellular respiration. However some plants called CAM plants open their stomas at night. The main reason for this process is due to the physical environment the plants are located in. The majority of CAM plants are located in hot, dry and desert environments where water is scarce. As a result the CAM plants evolved so that they could close their stomas during the day and open them at night, to help retain water, at night the plants can still absorb CO2. Some examples of CAM plants are, cacti, pineapples, and aloe.
Stomas can be opened or closed depending on climateric conditions.
Stoma are found in the leaves and stems of many plants, and its primary function as we know today is for gaseous exchange, specifically the stomata allow for easy passage of oxygen and carbon dioxide, molecules used in photosynthesis and respiration, respectively.
This colostomy involves the creation of two separate stomas on the abdominal wall. The proximal (nearest) stoma is the functional end that is connected to the upper gastrointestinal tract and will drain stool. The distal stoma
