Typical EEL spectra of P-rich and N-rich inclusions.

(A) Spectrum of P-rich inclusion in Chlorella vulgaris IPPAS C-1. (B) Spectrum of N-rich inclusion in Chlorella vulgaris IPPAS C-1. (C) Spectrum of N-rich inclusion in Nostoc sp. PCC 7118. The hatched rectangle in the EEL spectra indicates the range used for fitting of the power law function representing the background for subtraction. Inserts in (B) and (C): enlarged part of the same spectra background-corrected using the range just before the peak of N.
