Demonstration of variability of fluorescence pattern depending on different growth stages during early exponential, exponential and stationary phase for all nine species. Presented as Chl a fluorescence excited by a 488 nm (x-axis) and a 561 nm laser excitation (y-axis). Yellow dots represent senescent cells during stationary phase, light green, blue or brown dots represent cells growing in early exponential phase and green, blue or brown dots represent cell growing in exponential phase
