The analysis of high resolution spectra of the Fe I (522.5 nm, 557.6 nm) and Ca II K (393.3 nm) lines in the solar photosphere and chromosphere is presented. A dynamic coupling of the photosphere and chromosphere was determined from the ratios of both the photospheric and chromospheric line characteristics. All results are discussed for quiet and pla ge regions. It is found that in the plage region the mean values of K1, K2, K3 intensities in Ca II K are increased 2, 5 and 6 times, respectively as compared to the quiet region. The mean values of Fe I line core intensities increased in plage only 1.32 and 1.64 times for the magnetic non-sensitive and magnetic sensitive line, respectively. The ranges of Fe I core intensity values are larger for the magnetic sensitive line than for the magnetic non-sensitive line.
