All living organisms are made up of cells, which are microscopic fundamental units. Every living thing has cells the main categories (Kingdoms) of living things are bacteria, protozoans, fungus, plants, and animals. Some organisms are made up entirely of single cells (e.g. bacteria and protozoans). Animals, including humans, are multicellular, though. An adult human body contains over 100 trillion cells! Each cell requires basic needs in order to survive. The organ systems of the body are mostly designed to meet the basic demands of the body’s billions of cells.
