Key regulators of stomata are plant vacuoles ... which are equivalent in function to lysosomes in mammalian cells (Figure 1). A special feature of guard cells is that they can increase or decrease ...

excessive evaporation might lead to desiccation and an equally severe disruption of photosynthetic function. Thus, one might expect plant leaves exposed to drought conditions to have fewer stomata in ...

It moves by diffusion through small holes in the underside of the leaf called stomata. Guard cells control the size of the stomata so that the leaf does not lose too much water in hot, windy or ...

Plant stomata, which consist of paired guard cells ... closes the stomatal pore and the first component for this channel function has now been found. You have full access to this article via ...

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.
