To avoid this, an individual plant may open its stomata and evaporate water which will lower the leaf temperature. Thus, one may hypothesize that leaves in the sun should have higher stomata density ...

In this lab, stomata density variation likely results from interacting ... Most students have not seen the basic concepts of statistics we expect them to use in this experiment. The instructor must ...

Growing the trees outdoors is important for our experiment, because we want ... the relationship and use the number of stomata on a fossil leaf to calculate the amount of carbon dioxide in the ...

but using the “Breathing Leaf” experiment, we can turn the unseen into the visible. Here’s how it works: First you will need: A clear bowl Water An active leaf (one pulled off a plant ...

Through small openings on the leaf, called stomata, a tree can regulate moisture and gasses. With the exchange of water and the absorption of carbon dioxide during the process of photosynthesis ...

On the lower half of the leaf are spongy mesophyll cells. These have air spaces between them to let gases flow. The stomata - tiny openings or pores – allow gases such as carbon dioxide and ...
