The Cell The cell is possibly the most important concept in biology since it is the basic unit of life. Every living organism is made up of cells (or just one in the case of bacteria). Your body is composed of microsopic cells that are only visible if viewed under a microsocope. All the animals, trees and plants are made up of cells that share many similar characteristics. They all have cell membranes separating them from the outside environment, DNA to store information, RNA to pass this information to the ribosome- and ultimately protein that is translated from the RNA (mRNA to be specific). These common features make it possible to learn clues about how our own cells function by studying the cells of other model organisms like mice, fruit flies or nematodes. Most organisms that we are used to seeing are multicellular and have different types of cells that are suited for a particular function. Bacteria are composed of a single cell but also share the same characteristics just described. There are a few important differences though that will be explained
