single celled organisms need something to live on. They do not reproduce they use Bionary Fission

They grow when they eat and need living space. Just like the rodefer in the tank. You can find germs on everything. By the way, if something is sterol like in dental offices, does that mean theres no germs on it at all?

Single-celled organisms are species that are microscopic,and they dont have many abilites to do things, such as Esherichia Coli

Single celled organisms are usually microscopic but some can be seen without a microscope. Like multicellular organisms there are predators and prey, such as a Didinium and a Paramecium. Also there are animals such as a Euglena who have chlorophyll to help them make food. Most single celled organisms use binary fission, where one cell splits into two identical cells.

Bacteria are germs that can grow and just about anything. Bacteria can also carry diseases that may get you sick

I think they need a place to live, and they grow when they eat, and they can move...I think, and they reproduce like all living things except in a different way...
