In botany, a stomata is a pore, found in the leaf and stem epidermis that is used for gaseous exchange. The pore is bordered by a pair of specialized [parenchyma] cells known as guard cells that are responsible for regulating the size of the opening. The term stomata is also used collectively to refer to an entire stomatal complex, both the pore itself and its accompanying guard cells. Air containing carbon dioxide and oxygen enters the plant through these openings where it is used in photosynthesis and respiration, respectively. Oxygen produced by photosynthesis in the spongy layer cells (parenchyma cells with pectin) of the leaf interior exits through these same openings. Also, water vapor is released into the atmosphere through these pores in a process called transpiration.

Stomata are present in the sporophyte generation of all land plant groups except liverworts. Dicotyledons usually have more stomata on the lower epidermis than the upper epidermis. Monocotyledons, on the other hand, usually have the same number of stomata on the two epidermes. In plants with floating leaves, stomata may be found only on the upper epidermis; submerged leaves may lack stomata entirely.

Hermenegildus "Herman" Felix Victor Maria Finkers (born December 9, 1954 in Almelo, Overijssel) is a comedian from the Dutch region of Twente, who is well-known in the Netherlands for his friendly, dry-witted humour and his ambiguous style of storytelling. In his way of telling a story the moral should never be in the way of a good joke or pun. His humor is never at the expense of others, except his brother Wilfried Finkers, who is frequently the target of jokes. Wilfried Finkers co-wrote material and occasionally appeared in his brother's shows. Herman Finkers temporarily stopped performing in 2000, and soon afterwards he was diagnosed with a form of leukemia. He was given an estimate of 10 to 15 years of life left. On August 5, 2006 a Fuchsia was named after him. In 2007 he started playing in theatres again, with a new show called "Na de Pauze" (After the Intermission).

Finkers has a strong love for the Twents dialect. He has translated a number of his shows into Twents Low Saxon, which is his mother tongue. He also wrote and directed two short animation films, which were completely in Twents: Kroamschudd'n in Mariaparochie (which tells the story of the birth of Christ in a Twents setting) and his comic interpretation of William Shakespeare's MacBeth, the former of which is shown annually around christmas on regional television. After his retirement from theatre, Finkers played a role in the first Soap series in Twents: "Van Jonge Leu en Oale Groond" (Of Young People and Old Ground). For his efforts to promote the Twents dialect he received the Johanna van Buuren prize.
