To understand stomata behavior, we wanted to be able to measure the pressure in the guard cells—but it's not easy. Enter Craig Brodersen of Yale University with a newly developed microscope ...

Get Instant Summarized Text (Gist) A new laser-based method has been developed to observe pressure changes in plant stomata, enhancing the ability to study plant physiology and evolution. This ...

Put a small drop of water on a microscope slide ... Area = πr 2 = 3.14 × 0.20 × 0.20 = 0.13 mm 2 The number of stomata in the field of view is 12.

In this field of view, there are 12 stomata - nine open and three closed. The images show the fields of view of a plant leaf viewed with a microscope. Count the number of stomata in each sample.
