We are increasingly confronted with the impacts of climate change, with failed harvests being only one example. Addressing these challenges requires multifaceted approaches, including making plants ...

Scientists discovered that certain plants can survive stressful, dry conditions by controlling water loss through their leaves without relying on their usual mechanism -- tiny pores known as 'stomata' ...

Stomata open in response to blue light, and close in the presence of abscisic acid (ABA), which is biosynthesized when the plant is under dark conditions and/or drought stress. Stomata are essential ...

I always assumed Clark Moorten watered the cactus at night because the Botanical Garden was closed. But now I'm thinking he had another big reason to set up his sprinkler on the agave and cactus to ...

correlation and causation: Many students do not understand the fundamental difference between correlation and causation. In this lab, stomata density variation likely results from interacting ...

Open (left) and closed (right) stomata found on the surface of plants' leaves, stems and other organs. Through the stomata, plants exchange oxygen and carbon dioxide, and lose more than 95 percent of ...

Plant behavior may seem rather boring compared with the frenetic excesses of animals. Yet the lives of our vegetable friends, who tirelessly feed the entire biosphere (including us), are full of ...

Plant stomata play a role in water loss and carbon dioxide uptake from leaves. A researcher has found that the plant hormone abscisic acid underlies the differences in certain critical features of ...

Cellulose acetate replicas were made from silicone rubber impressions of the abaxial surfaces of perennial ryegrass leaves. Apertures between 1 μ and 4 μ (mean 2 μ) were measured in replicas from ...
