Definition of stomate in English: stomatenoun ˈstəʊmeɪtˈstōmāt Botany another term for stoma Example sentencesExamples - Quercus rubra leaves have about 150 million stomates per m (= N) and stomatal pores with a major axis of about 10.7 m (= a).
- Some starch can also be seen in the guard cells of stomates.
- This can be due to a reduction in light interception as leaf expansion is reduced or as leaves senesce, and to reductions in C fixation per unit leaf area as stomates close or as photo-oxidation damages the photosynthetic mechanism.
- This capacity is due to the presence of stomates on both leaf surfaces, permeability of tissues for CO 2 diffusion and an intense Rubisco activity.
- This makes it unlikely that stomates closed because of a leaf water deficit and raises the possibility of regulatory signals coming from the roots.
Origin Mid 19th century: apparently an English singular of stomata.
