If you mean a surgically created opening to the urinary bladder or to the intestines, or for a tracheostomy, they are open. e.g. A stoma IS always open. A temporary stoma may be made and later closed, but by definition, stoma is an "opening".1. Picture of trach stoma. - This shows a trach stoma cap which protects the stoma.2. Picture of a loop ileostomy. -- Whether the stoma opens to bowel or bladder, the outside of the stoma appears basically the same. If for bladder, a small flexible tube is kept put through the stoma; a see-through "bag" attached to the skin (or upper thigh) collects the urine which the person must dump. The tubing is replaced periodically. If for bowel, a see through pouch is affixed onto the skin, over the stoma, to collect feces. The feces must be 'dumped' also.On any stoma, the area must be cleansed or the tender tissue can break down, bleed, become infected, etc.
because when stomata open, they will take carbon dioxide in, so stoma need air space to hold carbon dioxide.
The cells that make up the stoma are known as guard cells. These specialized cells are responsible for regulating the opening and closing of the stomata to control gas exchange and water loss in plants.
Guard cells are able to control how open or closed stomata are by changing shape. The gas exchange occurs when stomata are open facilitates photosynthesis
Stoma tend to be closed on a hot day to minimize water loss through transpiration, as high temperatures can increase the rate of transpiration. This helps the plant conserve water and maintain proper hydration levels.
The stomata closes duirng the night when there is no light, this is because photosynthesis only takes place during the light and that is when the stoma is open , to let in carbon dioxide for photosynthesis. Otherwise it is closed. =D hope this helps
The stoma opens and closes to allow gas exchange. The Guard cells are located around the stoma and regulate the opening and closing of the stoma.
Well, Depending on how old you are, it could be a growth plate.
The Guard cells
Guard cells change shape to open and close stomata. When they are flaccid, the stoma is closed. When they are full of water and firm, the stoma is open. There are 2 guard cells controlling a stoma. Water enters guard cells by osmosis and they change shape.

Stoma
On a Sunday WHSMITH closes at 7pm

No the flexor closes the joint.
