Definition of photic in English: photicadjective ˈfəʊtɪkˈfōdik technical 1Relating to light, especially as an agent of chemical change or physiological response. Example sentencesExamples - Furthermore, extraretinal photoreceptors appear to be involved in the photic entrainment of the circadian clock.
- To characterize this photic entrainment we examined frq expression in constant light, under which condition the mRNA and protein of this clock gene were strongly induced.
- The implications of this work on thought about evolution of photic behavior in fireflies are considered.
- They are therefore true deep-brain photoreceptors that bypass the eyes as a pathway for photic information.
- Exhibiting uncharacteristic panache, John used this result to question Jacques Loeb's then popular theory of photic orientation in insects, which required paired eyes.
- Complementing the large compound eyes, locusts have three much smaller simple eyes or ocelli characterized by rapid signal transmission and high photic sensitivity but very poor spatial resolution.
- 1.1Ecology Denoting the layers of the ocean reached by sufficient sunlight to allow plant growth.
an average depth for the photic zone is about 100 m Example sentencesExamples - Seasonal highs that pushed this euxinic layer into the photic zone would then lead to the greatly increased preservation and the TOC maxima.
- The authors skimmed their bacteria samples from the top, or photic layer, of the Mediterranean and Red Seas.
- Stromatolites were built by photosynthesizing organisms occupying shallow-water environments within the photic zone.
- The relatively moderate brachiopod generic diversity is consistent with a moderately restrictive environment, including one below the photic zone.
- Macroalgae benefit from this relationship because fertile drift plants are retained in the photic zone where they continue to contribute to the gene pool.
