the radius is 0.20 mm. Area = πr 2 = 3.14 × 0.20 × 0.20 = 0.13 mm 2 The number of stomata in the field of view is 12.

How do plants breathe through stomata? Key regulators of stomata are plant vacuoles, fluid-filled organelles bound by a single membrane called the tonoplast. Plant vacuoles are fluid-filled ...

To be representative of the whole leaf, the representative sample must: include a sufficient number of counts - not just one or two - of stomata over different parts of the slide must be random ...

Because of these properties, the majority of plant gas exchange occurs through stomata. Consequently, composition of cuticle and fast guard cell signaling are thought to be the major factors limiting ...
