I know that bacteria is extremely small but more bacteria means bigger ball of bacteria.
In: Biology
When they’re not growing in a culture as mentioned, they’re actually spread out a bit. They’re relatively translucent, also, meaning they don’t have much color to them. Under a microscope, you can see straight through them and all their internal workings. They typically spread out randomly, aside from avoiding competing colonies and other things that would eat or kill them, so they aren’t “heaped up”, but more spread out like a handful of sand on a countertop.
You actually can! That’s what a Petri Dish does, it provides an environment where bacteria can reproduce so much that they create a spot visible to the naked eye. That’s also what mold on bread is; just loads of microbes in such a large heap that you can see them.
In most normal situations, you can’t see bacteria because they are quite spread out.
You can see bacteria when you grow them on a petri dish, they grow in concentrated, clonal colonies 😎
Isn’t that pink stuff that sometimes appears in bathrooms around drains and in showers bacteria?
