Ib nqus spectrum qhia tag nrho cov xim ntawm lub teeb nqus tau los ntawm tsob ntoo. Ib kev ua spectrum qhia tag nrho cov xim ntawm lub teeb uas siv rau hauv photosynthesis . Chlorophylls yog cov xim ntsuab uas nqus liab thiab xiav thiab koom nrog photosynthesis ncaj qha.

Hauv qhov no, qhov kev sib raug zoo ntawm qhov nqus spectrum thiab qhov kev ua spectrum yog dab tsi?

Ib nqus spectrum txhais cov spectrum ntawm electromagnetic hluav taws xob, los yog lub teeb, cov nroj tsuag nqus. Qhov no nyob ntawm lub cellular thiab molecular build-up ntawm cov nroj tsuag. Ib kev ua spectrum txhais cov spectrum ntawm electromagnetic hluav taws xob zoo tshaj plaws rau photosynthesis.

Tsis tas li ntawd, dab tsi yog qhov kev ua spectrum hauv photosynthesis? Ib kev ua spectrum yog ib daim duab ntawm tus nqi ntawm cov kev ua tau zoo lom neeg uas tau npaj tawm tsam wavelength ntawm lub teeb. Piv txwv li, chlorophyll muaj txiaj ntsig zoo ntawm kev siv thaj chaw liab thiab xiav dua li thaj tsam ntsuab ntawm lub teeb. spectrum mus ua photosynthesis.

Ib yam li ntawd, qhov nqus spectrum cuam tshuam li cas rau photosynthesis?

Pigments nqus lub teeb siv hauv photosynthesis . Hloov chaw, photosynthetic kab mob muaj lub teeb- nqus tau molecules hu ua pigments uas nqus cov wavelengths tshwj xeeb ntawm lub teeb pom kev, thaum xav txog lwm tus. Cov txheej txheem wavelengths nqus tau los ntawm ib tug pigment yog nws nqus spectrum.

Vim li cas qhov kev txiav txim spectrum rau photosynthesis qhia kev ua haujlwm dav dua?

Cov carotenoids pab sau rau hauv nqus qhov khoob ntawm chlorophyll thiaj li loj dua ntawm lub hnub spectrum tau siv. Lub zog absorbed los ntawm cov "antenna pigments" yog dhau mus rau chlorophyll qhov twg nws tsav lub teeb pom kev ntawm photosynthesis . Ntau yam khoom nqus ultraviolet thiab/los yog infrared rays.
