What is the role of guard cells do in the leaf?

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.

Why a stoma may be fashioned?

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.
