aah ok thank you! so the color i see is just millions of bacteria that grew because of the “food”, nutrients they got on the agar plate? :) but how is it possible that some bacteria are pink or purple while others are white-yellowish?
Is there anyone who knows how agar plates work? Because my question is: when you test a material, after a few days you can see bacteria grow in your agar plates. But how does this happen? why is it suddenly visible?
I really want to know! :O Pls message me when you know the answer thanks! :)
