Mount Makiling is a  dormant   volcano  located on the border of  Laguna province  and  Batangas  on the island of  Luzon ,  Philippines . The mountain rises to an elevation of 1,090 m (3,580 ft)  above mean sea level  and is the highest feature of the  Laguna Volcanic Field . The volcano has no recorded historic eruption but volcanism is still evident through geothermal features like mud spring and hot springs. South of the mountain is the Makiling-Banahaw Geothermal Plant. The  Philippine Institute of Volcanology and Seismology  (PHIVOLCS) classifies the volcano as  potentially active . Mount Makiling is a state-owned forest reserve administered by the  University of the Philippines Los Baños . Prior its transfer to the university, the mountain was the first  national park  of the Philippines.  Mount Makiling National Park  was established on February 23, 1933 by ...

Mount Pinatubo Mount Pinatubo  ( Sambal :  Bakil nin Pinatubu ;  Kapampangan :  Bunduk/Bulkan ning Pinatubu, Bunduk ning Apu Malyari ;  Pangasinan :  Palandey/Bulkan na Pinatubu ;  Ilokano :  Bantay Pinatubo ;  Tagalog :  Bundok/Bulkang Pinatubo ) is an  active   stratovolcano  in the  Zambales Mountains , located on the  tripoint  boundary of the  Philippine provinces  of  Zambales ,  Tarlac  and  Pampanga , all in  Central Luzon  on the northern island of  Luzon . ]  Its eruptive history was unknown to most before the pre-eruption volcanic activities of 1991, just before June. Pinatubo was heavily  eroded , inconspicuous and obscured from view. It was covered with dense  forests  which supported a population of several thousand indigenous  Aetas .

Leaf Stomata a  stoma  (plural "stomata"), also called a  stomate  (plural "stomates")(from  Greek   στόμα , "mouth"), is a pore, found in the epidermis of leaves, stems, and other organs, that facilitates  gas 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 stomatal opening. The term is usually used collectively to refer to the entire stomatal complex, consisting of the paired guard cells and the pore itself, which is referred to as the stomatal aperture. Air enters the plant through these openings by gaseous  diffusion , and contains  carbon dioxide  and  oxygen , which are used in  photosynthesis  and  respiration , respectively. Oxygen produced as a by-product of photosynthesis diffuses out to the atmosphere through these same openings. Also,  water vapor  diffuses th...
