Detailed explanation-1: -Leaf stomata are the primary sites of transpiration and consist of two guard cells that form a small pore on the surfaces of leaves. The guard cells control the opening and closing of the stomata in response to various environmental stimuli and can regulate the rate of transpiration to reduce water loss.

Detailed explanation-2: -Stomata consist of microscopic pores, each flanked by a pair of guard cells. Guard cells can increase or decrease the size of the pore via changes in their turgor status, hence regulating both CO2 entry into the leaf and transpiration, or the loss of water from the leaf.

Detailed explanation-3: -Stomata are responsible for allowing gas exchange between the inside of the leaf and the atmosphere. Stoma is the singular and stomata is the plural form.

Detailed explanation-4: -Stomata resemble doughnuts-a circular pore with a hole in the middle for gas to enter or leave the plant. The pore consists of two cells-each known as a guard cell.

Detailed explanation-5: -A stoma is an opening on the abdomen that can be connected to either your digestive or urinary system to allow waste (urine or faeces) to be diverted out of your body. It looks like a small, pinkish, circular piece of flesh that is sewn to your body. It may lie fairly flat to your body or protrude out.
