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 ...

Marius Floriancic runs quickly along a narrow, well-trodden path, heading deeper and deeper into the forest. It is a cool, ...

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 ...

Stomata - microscopic valves on the surface of a leaf's epidermis - are at the forefront of these trade-offs: stomata open to acquire fresh air (and the carbon dioxide in it) for photosynthesis, but ...

through special leaf structures, and even through their stomata. But some trees, including coast redwoods, live in both wet and dry environments with intense seasonal variation. For broad-leaved ...

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 ...
