Pluralstomata(stō′mə-tə) 1.BotanyOne of the tiny openings in the outer surface of a plant leaf or stem, through which gases and water vapor pass. Most stomata are on the underside of leaves. 2.ZoologyA mouth-like opening, such as the oral cavity of a nematode. ...
What is stomata in plants? Stomata are openings in between guard cells that allow plants to exchange gases, such as carbon dioxide and water vapor, with their outside environment. What is a function of stomata in leaves? Stomata regulate gas exchange between the plant and the outside environme...
Plants don't have muscles, but they have a specialized structure that opens and closes stomata called guard cells. These cells pump ions such as calcium and potassium in and out of the cell, causing the cell to contract, resulting in the stoma opening or closing. This is similar to the ...
At night, the stomata become closed to save water and energy, even though excess water may still need to escape. The process of guttation offers a method for water to escape via the hydathodes, or small openings in the leaves of a plant. Is guttation bad for plants? Guttation is a ...

–In semi-arid regions or regions with very hot and dry environmental conditions, plants are forced to close their stomata in order to limit water loss. Under such harsh conditions, the intake of CO2 decreases during the day as the stomata are forced closed. This might lead to no CO2 intak...
An example of excretion is the process of transpiration in plants. Through transpiration, excess water is excreted from plants through stomata (pore-like structures) on leaves, as well as from the surfaces of fruits and stems.What is Excretion? The definition of excretion is any process through...
