How does the size of yogurt bacterium compare to that of the animal cell?

Yogurt bacteria, such as Lactobacillus and Streptococcus, are typically much smaller than animal cells, measuring around 1 to 3 micrometers in length. In contrast, animal cells generally range from 10 to 30 micrometers in diameter. This size difference highlights the complexity and multicellularity of animal cells compared to the simpler, unicellular structure of yogurt bacteria.
