Stomata play an important role in photosynthesis as they allow the plant to absorb carbon dioxide from the environment. In exchange, stomata allow oxygen, which is a waste product of photosynthesis, to be released. In the process, water vapor is also lost as the internal parts of the leaves are exposed. To reduce exposure, stomata are found on the underside of the leaves. They are protected from the sun as excessive heat can increase the rate of water vapor leaving and thus wither the plant. Stomata also have guard cells around the epidermis that close when too much water is being lost.
If you're looking for a quote regarding using sunlight as a source or energy, a quote by Maria Telkes would be '"Sunlight will be used as a source of energy sooner or later..." she said. "Why wait?"'
Answer:
Cuando escucho hablar sobre la tabla periódica se viene a mi mente que es una forma de organizar todos los elementos que existen.
Explanation:
La tabla periódica tiene como fin organizar a la gran diversidad de elementos químicos que existen agrupándolos según sus propiedades. De esta forma, podemos ver que elementos tienen cualidades similares entre si y predecir como reaccionarían con otros elementos de la tabla periódica. En otras palabras, es una forma ordenada y simple de mostrar las características de cada elemento y articularlo con los demás según sus características.
The answer should be coal.
Hope this helps
