WebOct 23, 2024 · Food vacuoles in 20 Paramecium cells were counted under light microscopy (Olympus, BX51). Data were represented as averages based on triplicate samples from three identical experiments. To evaluate the cell division rate, the numbers of cells at the start of culture were aligned in 100 cells/mL and cultured without adding any bacteria.
