Austin and Marissa should observe the number of open stomata on one leaf, mist the leaf with water, wait one hour, and count the number of open stomata again.
In the epidermis of tree leaves and needles, there are cell structures called stomata that play a role in the exchange of water and carbon dioxide between plants and the atmosphere.
Stomata, the tiny pores on the outside of leaves and stalks, control how gases enter and exit leaves and therefore, how plants as a whole function. On all periods, ranging from minutes to millennia, they adjust to regional and global changes.
Guard cells are a pair of specialized epidermal cells that make up stomata. By adjusting the size of the stomatal pore, stomata govern water loss and the exchange of gases between the plant and its surroundings.

A, electro magnetic is not a form of potentional energy
We can tell from their structure that fatty acids are a good source of energy because of their large number of carbon-hydrogen and carbon-carbon bonds that they contain. Most fatty acids have straight chain compounds with an even number of carbon.
